In the early thirteenth century, the Mongols, who were originally part of the Jin Dynasty, unified the Mongols and established the Mongol Khanate under the leadership of their leader, Genghis. Mongol Khanate in the process of expansion to the south, in 1227 A.D. destroyed Western Xia, 1234 A.D. destroyed Jin, encroached on the Central Plains, so the formation of the Southern Song Dynasty and Mongolia confrontation situation. There was a long war between the Song and the Mongols.

Southern Song Lizong (Zhao Yun) Bao You six years (1258 AD) in February, Mongolia Khan Meng ordered, divided into three roads to attack the Song. The middle road by the royal brother Kublai led the attack on Ezhou (now Wuchang, Hubei); East Road by the Tachaer led the attack on Jingshan (now Huaiyuan, Anhui), but also made the general Uliang Hetai by the Jiaogong (now Vietnam), wide (now Guangxi) to lead the troops to the north; the West Road by the Mongkol personally led the main force, attacking Sichuan. At that time, Meng's plan was, after the capture of Sichuan, the three-way division Ezhou (now Wuchang, Hubei), and then attacked the capital of the Southern Song Dynasty Lin'an [now Hangzhou, Zhejiang].

Bao You seven years (1259 AD) in February, the Mongolian army attacked to Hezhou Diaocheng (now Sichuan Hechuan city northeast) under the city, Meng personally supervised the division, surrounded on all sides. Wang Jian was not cowed by the enemy's strength, and was not shaken by the enemy's temptation to surrender. He led the whole city's army and people, and with the heavenly danger of Diaoyuocheng's terrain, he resisted valiantly, and crushed the Mongolian army's attack. The Mongolian army's vanguard, Wang Dechen, was wounded and died under the counterattack of Wang Jian's fierce cannon, and Mong himself was wounded and died in the army, and the Mongolian army had to retreat northward. The victory of Diaocheng against Mongols reversed the whole situation of the war, and the dying Southern Song Dynasty was able to get through the crisis, and the Han Chinese people were saved from being ravaged and enslaved by the Mongol rulers. For this reason, the military and civilians in the Diaoyu Mountain cliffs, engraved a huge inscription, the text with? The inscription used the words "Jian supported half of the wall with a pillar of Fish Town" to praise Wang Jian's great achievements in this battle. The words of the inscription celebrated Wang Jian's success in this battle and wrote a glorious page in the history of the nation.

Wang Jian was originally a member of the Xingyuan people's patriotic anti-Mongolian armed forces, the Xingyuan people's armed forces to accept the leadership of the Southern Song Dynasty general Yu Shi, Wang Jian was appointed by the Song Dynasty as the Wugong Daifu. In the 10th year of the reign of Emperor Chunyou (1250 AD), Yu Jie led them to recover Xingyuan (present-day Nanzheng, Shaanxi Province), and Wang Jian was appointed as the ambassador of Yaoxian County Regiment. In the first year of Bao-You of Emperor Li Zong (1253 A.D.), Yu Jie died violently and sent Wang Jian to be the governor of Hezhou (Diaoyu City), and in the next year, he was appointed as the governor of Xingyuan Dutong to know Hezhou.

Diaoyu City was on Diaoyu Mountain, northeast of present-day Hechuan City in Sichuan. Although not very high, Diaoyu Mountain is very steep and rises out of the ground, standing on the north bank of the Jialing River. From the north to the west, the Jialing River and the Drainage River in the north of it not far from the confluence, around the Diaoyu City to the west, flowing to the city of Hechuan, the Jialing River and the Fulingjiang River confluence, embracing it folded to the east, to the ground around a tortoise head shaped peninsula, the north, the west and south of the three facing the water. Diaocheng is the highest place on this peninsula, it is high, control the three rivers. It is surrounded by Yunmen Mountain, Tiger Mountain, Hutong Mountain, Horse Hill, Shizishan, Fortress Hill, South Drainage, Sanjiangkou, Jijiazha Beach, Pingyang Beach and other dangerous as a barrier to the situation of the ancient wars, is really a place where the soldiers must fight.

Diaoyu City not only has the above superior geographical conditions, but also from the Chunyou two years (1242 AD) began to build the city, it has carried out some painstaking management. Fishing City **** there are nine gates: Guoguo, Qinghua, Zhenxi, Dongxin, out of Qi, Qi Sheng, small East, the beginning of the pass, water hole. The highest part of the city wall reaches twenty early. And in the middle of the two cliffs facing each other outside the city to build a word city as a barrier. Inside the city to attract the sky stream ditch water for the pool, around more than a hundred paces, called Tianchi. The spring was so full of water that it never dried up in the morning. Thirteen small pools and ninety-two wells were opened. As a result, the drinking water and irrigation supply for the residents of the city were effectively guaranteed.

Wang Jian to Diaoyu City, mobilized the state belongs to the people of Shizhao, Tongliang, Bachuan, Hanchu, Chishui five counties to strengthen and repair Diaoyu Mountain City, Diaoyu City is more solid; at the same time, reduce the administration, save military expenditure to reduce the burden of the people; to the people to the land, to inspire them to carry out agricultural production; and called by the Mongolian army infestation of people from all over the Diaoyu City to rebuild their homes, so the Qin (present-day Tianshui, Gansu), Gong (present-day Tianshui), Gong (present-day Tianshui), Gong (present-day Tianshui) and Gong (present-day Tianshui). Therefore, the people of Qin (present-day Tianshui, Gansu), Gong (present-day Longxi, Gansu), Li (present-day Guangyuan, Sichuan), and Shuai (present-day Luoyang, Shaanxi) all moved to Diaoyu City, which made the city a town of more than 100,000 people. As a result, Wang Jian's Diaoyu City was able to hold out and fight with strength.

In the first month of the second year of Song Baoyou (1254 AD), the Mongol invasion of Guang'an Army (present-day Guang'an North, Sichuan Province) came to the border of Hezhou, and was repulsed by the army and people led by Wang Jian. This was the first blow given to the Mongolian army by Wang Jian and the people of Diaoyu City.

In the fourth year of Baoyou (1256 A.D.), Meng ordered the general Ulianghedai to open the road to Sichuan.

In April of the fifth year of Baoyou (1257 AD), the Mongol army captured the Bitter Bamboo Pass and peered into Jianmen (north of present-day Jiange, Sichuan), preparing to build a fortress, which was unsuccessful due to the tight defense of the Southern Song army and people.

Bao You six years (1258 AD) in February, the Mongolian army invaded the Song Dynasty, the Khan Mongkol since the rate of 40,000 troops, known as 100,000, from the Liupan Mountains (now Gansu Guyuan) in three ways to attack Sichuan. All the way is the wood from Yangzhou (now Shaanxi Yangxian) directly attack Bazhou (now Sichuan Bazhong) Micang Pass; all the way is Soricha from the fishery pass into the Hezhou (now Shaanxi Hexian); Meng personally from the Longzhou (now Shaanxi Longxian) into the Dashanguan (now southwest of Shannxi Baoji) this way the fall of Lizhou (now Sichuan Guangyuan), Longzhou (now Sichuan Renshou), Shunqing. The Song generals of Mazhou (present-day Mazhong, Sichuan), Pengzhou (present-day southeastern Yilong, Sichuan), and Guang'an Army (present-day northern Guang'an, Sichuan) shamelessly surrendered. Thus, Meng, who was approaching Diaoyu City, was unbeatable and thought that Wang Jian would surrender without a fight in fear of his might, so he sent Jin Guobao, a surrendered general, to Diaoyu City to beckon Wang Jian to surrender. But his estimate was totally wrong.

Wang Jian not only refused to surrender, but also captured Jin Guobao and declared him guilty of surrendering and treason, and he was executed in public at the military training ground. When Meng heard that Wang Jian refused to surrender and killed Jin Guobao, he was furious, so on February 3 of the seventh year of Baoyou (1259 AD), he personally led his army to besiege Diaoyu City. Meng led the armies across the Jizhuatan to Shizishan and supervised the battle under the city.

From February 7 to the end of March, has attacked a word of the city, ZhenXiMenXiaFu, DongXinMen, QiShengMen, GuGuoMen, etc., are DiaoyuCheng military and civilian repulse. April 3 to 22, twenty consecutive days of heavy thunderstorms, the Mongolian army temporarily stopped the attack, thunderstorms stop, Mongolia and ordered the attack on the Protector of the State, the night of the twenty-fourth had once attacked the outer city. Wang Jian not only led the military and civilian defense, but also the use of the night open the city gate to raid the Mongolian army, thus forcing Meng to order Zheng Wen rate of 4,000 troops in the Diaoyu Mountain around the special patrols, or sleep at night is not restful. In May, the war still continued in Diaoyu City. But the Mongolian army from the northern desert area, the southern climate is not adapted, and after a heavy rain, followed by the heat, dysentery epidemic, the Mongolian army morale is low, the combat effectiveness is greatly reduced.

On the contrary, the people and army of Diaoyu City after months of fighting, plus Wang Jian and other leadership, the fighting spirit of the people and the army is even higher, the generals were able to sit on the city? The general was able to sit on the city? and commanded with ease. In a fierce battle, the Mongolian army general Dong Wenwei and other turns to the Diaoyu City attack, the result of the ladder by the city defending the soldiers and civilians with flying stones broken, soldiers and generals were killed and injured by flying stones, had to retreat. Dong Wenwei's nephew, Dong Shiyuan, who had just arrived from Dengzhou with his army, requested to continue the attack instead of Dong Wenwei, and personally led his elite troops to fight on the mountain, but the result was that they were still defeated, and Dong Shiyuan almost gave up his life. Fishing City held for several months, to fight against the Mongolian army of the Southern Song Dynasty military and civilians with great encouragement, the Li Zong also recognized:? Wang Jian infant city defense, a hundred battles, even far away in Lin'an, Song Jieyi for the crown of the city of Shu?

Late May, the Song general to Shibi to take advantage of the tailwind, broke the pontoon bridge in Fulzhou (now Fuling, Sichuan Province) Lin City, broke through to the A Bachi clamped the river for the camp, dozens of miles long blockade, the beginning of June, the Sichuan system of making the Lv Wende from Chongqing rate of more than 1,000 warships along the Jialing River, to save Diaoyu City, for the Mongolian Shi Tianze was defeated. The Mongolian army defeated Chang Wende's reinforcements, and then attacked Diaoyu City with great vigor. June 5, the Mongolian army's vanguard general Wang Duchen night selected elite troops boarded the outer city to attack, Wang Jian led troops to meet the battle, Wang Duchen can not enter, want to use to shake the military and people's division policy, so single rider to the city shouting:? Lu Wende's reinforcements have been defeated by us, Diaoyu City sooner or later will not be able to keep, you should surrender before it's too late, I guarantee that the people and army of the city will not die, do not look for death with Wang Jian recalcitrance? Before the words finished, a burst of flying stones on the city like rain hit, Wang Dechen was hit by flying stones, coincidentally, the sky is raining heavily, Wang Jian led the army and people out of the city to pursue, Wang Dechen rushed to escape back to the camp, soon died.

During the attack on the city, Meng lost his soldiers and was still unable to attack the Diaoyu City. He wanted to know what was going on inside the city, so he ordered his soldiers to build a tower outside the west gate, and erected masts on the upper floors, with flying cars on them, ready to send people up to spy on the reality inside the city. Wang Jian saw it in the city and knew that it was the enemy who wanted to observe the realities, and ordered the men to wait with their cannons in good position. On this day, he saw the flying car had just risen, and before he had time to see the city, the soldiers and people of Diaoyu City even used the cannons to hit, the flying arrows and boulders rained down as if they were raining down, the masts were broken, and the soldiers inside the flying car were thrown a hundred paces away and fell to their deaths.

Meng was leading troops stationed on the platform to supervise the battle at this time, and was wounded by the cannon fire (one said he was hit by flying stones). Wang Jian asked someone to fish up two live fish weighing thirty kilograms in the Tianchi pond, made hundreds of pastries, and sent them to the Mongolian camp with a letter telling the Mongolian ruler: ? You northern soldiers can cook fresh fish and eat noodle cakes, and you will not be able to break this city for another ten years? Mongolia see fresh fish and cakes, know that the city of drinking water and food are very sufficient, and see Wang Jian's letter, know that Diaoyu city military and civilian defense of the will is very strong, urgent can not be attacked, and their own and seriously wounded, generals due to injuries and illnesses and the death of a lot of people, had to retreat. The Mongolian army retreated to the sad military mountain, Meng's injury is heavy up, and through the Golden Sword Mountain Wentang Gorge, died of wounds. The Mongolian army in order to retaliate for Meng was killed in Diaoyu City, in the funeral on the way to the north, see people on the kill, along the way was killed by the innocent people up to 20,000 people.

Because the Mongolian main force was blocked in Diaoyu City, resulting in can't echo each other, can't achieve the plan of the three-way division of Ezhou. Meng died of injuries, Mongolia attacked Shu army retreat, the internal dispute over the throne. Kublai was eager to return to the north and fight for the throne, so he accepted Jia Sidao's plea for peace, and the Mongol forces attacking the Southern Song Dynasty retreated.

In this war, Wang Jian led the Diaoyu City defense war is a great role, it prevented the Mongolian elite main army from Shu east, and Kublai and other road army will meet, into and out of Lin'an, which makes the Mongolian army generals suffered great casualties, consumed the strength of the Mongolian army; especially killed Meng, so that the Mongolian ruling group of the internal division, to promote the withdrawal of Kublai and the other Mongolian army. This not only makes the dying Southern Song Dynasty, to be able to live twenty years, so that the Han people are temporarily exempted from the ravages of the Mongolian rulers and slavery, but also on the Mongolian army at the time of the war in Eastern Europe and Central Asia to have an impact. Because of the role of the defense of Diaocheng, South Song Duzong (Zhao Qi) Xianchun four years (1268 AD) early, in the Diaocheng near the construction of a temple to commemorate the Wang Jian, Heshou military and civilian and in the Diaocheng mountain cliffs, engraved a huge inscription, on the engraving? Jian supported half of the wall with a pillar of Diaocheng? to glorify the achievements of Wang Jian and the glorious page of national history written by the army and people of Diaocheng! Wang Jian's work, singing the glory of the Diaocheng military and civilian national history of a glorious page!

After the retreat of the Mongol army, the court of the Southern Song Dynasty awarded Wang Jian the title of Minister of the Ningyuan Army, and the title of "Kaiser of Qingshui County" for his contribution to the liberation of Diaoyuancheng. In the first year of Emperor Li Zong's reign (1260 AD), Wang Jian was transferred to Lin'an as an unoccupied official. In the fourth year of Jingding (1263 AD), Jia Sidao was jealous of Wang Jian's talent and sidelined him, ordering him to be the ambassador of Hezhou (present-day Hexian County, Anhui Province). Wang Jian felt that there is no way to serve the country, in March of the next year, and the state of the appointment of the depressed death, the end of the people let people lamented!
