The origin of water chestnut cake:
It is said that in the 23rd year of Zhenguan in Tang Dynasty (AD 649), Taizong died and Gaozong succeeded to the throne. Our envoy of Lingnan Road is known as horseshoe, lotus root, mushroom, bamboo shoot and water chestnut in Pantang, Guangzhou, so he ordered the painter to make a picture of "Five Shows in Pantang" and sent officials to present the picture and five objects to the DPRK. Emperor Gaozong was pleased with the picture and made it a sacrificial object for the throne.
Two-year-old Xianren was convicted of Wu Hou's crime, and he was forced to commit suicide. Xian has three sons, Guang Shun, Shou Li, Shou Yi, and Shun Shun are the King of Lean, and Yi Feng is condemned. Keeping righteousness is king, and moving to Guiyang. After Xianhe Guangshun passed away, Shouyi got the picture of "Pantang Five Show". Hanging arch for four years to keep righteous disease, Qiu prequel told the eldest son to bear ao and avoid Wu Hou's punishment. Cheng ao and his descendants went to sea by He, Wu and Annan, and entered Guangzhou in the first year of Tianfu in the late Jin Dynasty, where they lived in Zhijie and Julongli in Longxi.
Li Ji, a descendant of Cheng 'ao, moved to Pantang Village after he found the "Five Shows in Pantang". At that time, it coincided with the harvest of horseshoes, and Longkun ate fresh food according to local habits, which made him feel fragrant and sweet, so he kept some fresh horseshoes to be eaten later. Few fresh horseshoes began to rot, so Long Kun used the baking method, saying that the horseshoes were peeled, mashed and put in a kettle, and baked into powder by slow fire.
Boiling powdered water into paste and eating it with the villagers are all said to be the same as eating horseshoes fresh. Because it is made of "Pantang horseshoe", Long Kun called it "Pantang horseshoe powder". Subsequently, Longkun opened the Pantang Wuxiu store on the spot, selling Pantang horseshoe powder and Pantang Wuxiu products to the world. And "Pantang horseshoe powder" is today's water chestnut cake.
