Jingdezhen porcelain originated in the east township of Fuliang kiln (now Yao Li Village, Yao Li Township), since the middle of the Tang Dynasty, there are ceramic workshops here, to the Northern Song Dynasty has been a flourishing kiln, kiln dozens of places, porcelain workshops all over the place. Local villagers rich for business, that is, ceramics business workshop owners; skillful for the work, that is, porcelain production of skilled craftsmen to become a full-time artisan employed by the workshop owner. Workshop bosses to stimulate the production enthusiasm of craftsmen, improve product quality and yield, not only in the labor remuneration is reasonable, and three meals a day, plus a snack meal every day, as a way to compete for skilled craftsmen. In order to enrich the varieties of snacks, as early as the Northern Song Dynasty before the individual kilns and workshops created a new variety of snacks, namely, "alkaline water poi". Floating Liang folk called this "cake", because of the rice straw into the ash filtered water, it is called "gray water cake". Later, some people made a small round cake steamed on a cage drawer, it is called "gray fruit" (flooliang people on the whole steamed rice food collectively referred to as "cake"; made into a small steamed products collectively referred to as "fruit"). (the Furyang people call the whole steamed rice food "gao"; they call the small steamed products "guo"). This product is sliced into thin slices after cooking and frying the taste of flavor (thick alkali aroma), tough and smooth, crisp, distinctive flavor. After the household to household, village to village, to the Southern Song Dynasty, the vast majority of farmers in the county can master the production technology of this product.

Alkaline water poop in addition to being used as a snack for guests at home, because it is easy to carry, but also once became a mountain or to go far from home to work in the farmland of the dry food. According to legend, Yue Fei of the Southern Song Dynasty had led the Yuejia Army in Jiujiang and Hukou to fight against the Jin Dynasty; the people of Fuliang used to make "grey fruits" and sent them to Yue Fei's army to work for the army. Yuejia army and this product as marching food. In the Qing Dynasty, during the reign of Xianfeng, when the Taiping army was fighting in Fuliang, the people of Fuliang also used this product to comfort the Taiping army. During the period of the Land Revolutionary War, many farmers in Fuliang used this product to comfort the Red Army that fought in Fuliang and the Red Army guerrillas that persisted in the revolutionary struggle in the mountainous areas. Legend has it that the origin of alkaline water poop is related to Wu Zixu's visit to the grave of Hanwu at Zhaoguan in the Spring and Autumn Period. Jiu Gong Mountain belongs to the Mufu Mountain Range, which stretches across the border of Gan and E. "The mountain spans across Wu and Chu, with its sun belonging to Wuning and its yin belonging to Tongshan, and is called the Hundred Mile Hibiscus Roach." At the junction of the two provinces, now remains a semicircular arch, about 3 meters thick, about ten meters long, known as "Wu Chu Xiongguan", the old couplet: "half of the mountain down the sunny and rainy, a ridge east and west to judge Chu and Wu". Legend has it that Wu Zixu in the Spring and Autumn Period to escape the persecution of the King of Chu, in the Zhaoguan one-night rush white beard and hair, mixed out of the pass, Zhaoguan is here. Wuning known as "Wu head and Chu tail", JiuGongShan for the watershed between Wu and Chu, "Wu Chu XiongGuan" whether that refers to ZhaoGuan, so the legend to be examined. Besides, Wu Zixu mixed out of the Zhao Pass, the state of mind gradually leveled off, came to the halfway point of the depression, sitting on the ground, leaning against a tree to rest. He saw a large mound of earth not far away from the front, and there was a stone monument in front of the mound. Wu Zixu looked closely, the monument is engraved with the words "the tomb of the cold woman", the remnants of candles and paper ash all over the ground, the stone arch on the platform offerings are still there. Wu Zixu was so hungry that he chose a piece of fruit among the offerings to fill his stomach, and at this time he didn't care about its coldness, hardness, sourness and bitterness, and chewed it fiercely for a while, swallowing it in a few mouthfuls. When Wu Zixu was about to take the second one, a group of old and young people came from the depths of the forest, carrying bamboo baskets and sweeping the tomb. Wu Zixu was anonymous and only said that he came to Wu to join his relatives. Seeing that Wu Zixu was polite and courteous, the people took out offerings for Wu to fill his stomach. Wu Zixu chewed on a piece of fruit and listened carefully to the people's account of the origins of Granny Han. Granny Han, formerly known as Granny Han, lost her husband early, leaving behind three sons, the first son to garrison the border, the second son to guard the sea, and the third son was forced to leave for his husband's service, and there was no news of him. Han Granny looking forward to her children eager, day and night climbing the mountain to look out, in a blizzard, freezing to death in front of the slope. The townspeople for the coffin, repair the grave and set up a monument, named Han Granny's grave, the descendants of the blackmail called "cold Granny", leaving its anniversary of the 12th day of the first month of the rain and sunshine, the custom of predicting climate change in the early spring. If the sky is clear on that day, it will be said that Granny Han has found dry wood, and the weather in early spring will be good, on the contrary, it will be a bad weather with rain and low temperature. Wu Zixu listened to all the people's stories of Han Po's suffering and bowed down to the tomb, praying for Han Po's blessing to avenge him. When he saw the offerings in the baskets, which looked like cakes but not cakes and cakes but not cakes, he asked what they were. Only to know that Han died, the townspeople in the packing of their belongings, rice altar empty, stove cold pot cool, hanging on the beam of the bamboo basket only a few pieces of rice poop. Originally, the old and frail cold woman, relying on the townspeople to receive help to survive, because they see the crowd is not a good day, they came up with a diet, the rice grinding and steaming into the poop, every day, cut off a few slices, and to cook with wild vegetables. As the days went by, the rice became sour and hard to swallow. The old man looked at the deterioration of the rice poi worried, and suddenly remembered that women shampooing with grass burned ash filtered water, both fragrant, but also to remove dirt and grease, will try to use grass ash water mixed with rice syrup, and indeed can be stored for many days, not sour and not bad. Afterwards, whenever the anniversary of Han's death, the townspeople will make offerings of this poop to commemorate the anniversary. After visiting Jiu Gong Mountain in Qing Dynasty, many literati must go to Han's grave to mourn the unfortunate old man, and left a poem: "Half a bow of the crescent moon falls on the hillside, the stone teeth reveal more than one layer, the rain is as fine as paste grass like hair, the comb is still talking about Han's grandmother." One of the wonders of the Nine Palaces, "Han's comb", refers to this place. After Wu Zixu joined the state of Wu, he did his best to serve the state of Wu, but the king of Wu was an arrogant and foolish ruler, who listened to the interlopers of Yue and alienated Wu Zixu. Wu Zixu, remembering the tragic sufferings of Han Po and all the townspeople and worrying that the people of Wu would suffer from the war, passed on the method of making poi to the local people in case of emergencies, and it became the rice cake later on. The method is the same, but the ingredients and shapes gradually changed with the change of time and the different customs of the people. The Chinese government has been trying to make the rice cake a successor to the Chinese traditional rice cake!
