according to legend, it was in the late Ming dynasty. According to Li Qianlu, a martial disciple of the Tang family, when Zhang Xianzhong, the Eight Kings, entered Sichuan from Shaanxi, he set an ambush in Huangling City of Kaixian County, wiping out the main force of the Ming Dynasty in Sichuan, and then conquered Kaixian County. At that time, some of Zhang Xianzhong's troops were stationed in the area from Laoguanzui to Nanhe outside the city. Some soldiers crossed the Nanhe River to Sanzhong Village to cut sugar cane to eat, and they had an argument with a sugarcane forester in surnamed tang. Relying on a large number of people and weapons, the sergeant set off in an attempt to subdue the sugarcane master. Although this person was a long-term worker, he was a middleman in the Tang Dynasty. He used a hoe to hook left and stop right, and in a few rounds he paid the machinery of several soldiers. The sergeant who fled back was blamed for the war, so he invited long-term workers from surnamed tang to learn martial arts. Unexpectedly, the company commanders could not compete against him. Zhang Xianzhong was furious after hearing the newspaper, so he personally and his wife came to the Tang family disguised as merchants collecting sugar cane. The Tang family entertained the distinguished guest with double-skinned milk made of yellow milk and egg white with a unique gentle poison sucrose syrup. Zhang Xianzhong was so enraged by the sweet feeling after eating that he admired it and commended it to the Eight Kings. However, the Tang family knew that Zhang Xianzhong was a man and did not want to join the army and leave home, so he was sealed as a local military attache. At present, there is the tomb of this martial artist in Fuhou village on the outskirts of Kaixian county, and its tombstone has a title to test. Sugar Gate in Shu and Tangmen in Shu originated from rivers and lakes.

Tang people's unique martial arts skills, hidden weapons's ability to poison and strict family sect rules,

a sugarcane field and a willow forest have achieved and witnessed the eternal mystery of Sugar Gate in Sichuan.

With traveling around the Tang Clan in the Jianghu, double skin milk has been spread all over the country. It has become a gentle poison that fascinates both women and men.
