Xu Wei (1521-1593), with a long word, was named Tianchi, Tianchishan, Taoist of the Ivy League and Tian Shuiyue. Xu Wei was unhappy all his life, especially in his later years, when he was poor and miserable. He committed suicide nine times, went to prison seven times, and died of poverty and disease at the age of 73. Xu Wei was poor all his life, but he made great artistic achievements. He is proficient in calligraphy, painting, poetry and opera. Xu Wei claimed that "my book is the first, poetry is the second, writing is the third and painting is the fourth", but later generations gave the highest evaluation to his painting art, calling him the founder of China freehand brushwork school and the originator of the green school in the history of painting. He was not only called a "prodigy" by literary masters at that time for his outstanding artistic talent, but also became a historical figure widely praised by Shaoxing people and known to women and children for his witty words and deeds and legendary stories.
