Yelang existed in the Warring States, Qin and Han Dynasties. In the 6th year of Jian Yuan (BC 135), Emperor Wu of the Han Dynasty sent Tang Meng to South Vietnam and ordered South Vietnam to join the Han Dynasty. At this time, Ma Zhuang, a brilliant yelang soldier, was so arrogant that he didn't know there was a Han Chinese in the world. The well-known "which is bigger, Han or I" came from this mission, which also led to the collapse of Yelang country. One day, Tang Meng drank a drink called citric acid sauce, which was produced in Sichuan, South Vietnam. It was very delicious. He asked the merchant selling citric acid sauce where it was shipped to South Vietnam, and the merchant replied that it was shipped from Sichuan via the ZY(zhāngk) river in Yelang. After hearing this, Tang Meng had a brainwave, so he suggested to Emperor Wu of the Han Dynasty: Take Yelang and use Yelang's soldiers to sail down the river from ZY to attack South Vietnam. In the same year, Emperor Wu of the Han Dynasty ordered him to lead an army, take silk and money from his son to Yelang, occupy Yelang, and make it Qi 'an County ... From 28 to 25 BC, Yelang Wang Xing attacked Wang Yucheng, a dog and horse pond, and the satrap asked him to send his troops to fight against it. However, the imperial court of the Western Han Dynasty felt that the journey was too far to manage, so it sent doctors Zhang Kuang and Tai Zhong of Shu County to mediate. Yelang Wang Xing not only refused, but carved a wooden statue of Han Guan as a target and shot it on the side of the road to show hatred. The court of the Western Han Dynasty was furious and thought that mediation was useless. If we are not ready to attack, we will wait for the cool autumn. Autumn came, and the wise SHEN WOO's ZY new satrap Chen Li wiped out Wang Xing in one fell swoop.

The ending of things is really unexpectedly simple. In just three years, Yelang was finally destroyed by the Han Dynasty, and People's Republic of China (PRC) has been established for more than 200 years. After the dazzling brilliance, Yelang's night came to legend.

Guizhou was the frontier of Yelang in ancient times. Yelang is a small country, perhaps because of the inconvenient transportation caused by mountains all around at that time, so it is called Yelang arrogance.

According to historical records, Emperor Wu of the Han Dynasty sent envoys to the southwest to explore the passage from Chang 'an to India today. After more than a year's trek, Han Shi arrived in Yunnan and met Tao Qiang, the king of Yunnan. Once the king of Dian asked without ostentation, "Who is older, Han or me?" Later, China's envoy went to Yelang country, and Yelang Wang Duotong also asked the same question, "Which is bigger than Han?" . As a result, "arrogance" has become an allusion for people to ridicule conceited people. If we trace back to the source, the patent of "who is older than me" should belong to the king of Yunnan, and the king of Yelang cannot specialize in beauty. To find out the origin of this allusion is not to wash away the grievances of many people, nor is it necessary to regard the arrogance of Yelang as "the arrogance of the king of Yunnan". For Shi Lang's fascinating history and culture, we don't have to stick to our predecessors' lair, but we should recognize the historical reality and realistic needs and seek new solutions. According to Historical Records, "Yelang is the largest in the number of vassals in Southwest China." And he said, "Southwest barbarians are hundreds of years long, while Yelang dominates, while Yunnan is subject to Wang Yin". I don't need to blame myself for dominating the southwest, and I don't need to blame the pride and confidence of Yelang Wang. Moreover, the same question of "who is older than me in Korea" reveals Yelang Wang's desire for the outside world in a closed mountain. He yearned for the civilization of the Han Dynasty, was about to become an official, belonged to the Han Dynasty, was awarded the golden seal, and sent envoys to pay tribute to the capital. All this does not mean that he is arrogant. Yelang's national subjugation is not only because of his complacency, but also because of many historical grievances.
