Based on various historical materials, it can be generally confirmed that Quan Yi, also known as Xuanxuan and Yi Tong, was born in Zhang Sanfeng 1247 or 1248. Born in today's Heishan County, Liaoning Province, Baoji City, Shaanxi Province and Shaowu City, Fujian Province.

It is said that he looks extraordinary, with big ears and eyes, "turtle-shaped crane bone", a beard like steel wire, a bun on his head and a square ruler in his hand. No matter whether it is cold or hot, I just wear a patchwork coat and wander in the street. People have nicknamed me "Zhang Sloppy".

This Zhang Sanfeng doesn't talk much at ordinary times, but when discussing Buddhism, Confucianism and Taoism with him, Kan Kan talks in Kan Kan. "Based on virtue, righteousness, loyalty and filial piety, there is no false blessing or false disaster, which is deceptive. Therefore, heart and divine power, God and Tao, all things are established in advance. "

Zhang Sanfeng has two miracles. First, he climbs the mountain like a flat ground, and he can sleep in the snow in the dead of winter. Its physical quality stands out among the people who generally have insufficient food and clothing and weak constitution.

Secondly, in the early years of Hongwu, he established several strongholds in Wudang Mountain, so that his disciple Qiu Xuanqing lived in Wulong, Lu lived in Nanyan and Liu and Yang Shandeng lived in Zixiao. I set up a view in the north of Zhanqi Peak, named Palace, and built a house in the loess city, named Huixian Pavilion, so that disciple Zhou really kept it.

It can be seen that he has some business acumen. If he had lived to this day, he would not have lost to Li Yi.
