The author's introduction to leisure stories.

Li Yu (1611-1680), formerly known as Tian Zheng, was later renamed as Li Weng, a word Li Hong, a word.

Li Yu was originally from Li Xia Village, Lanxi, Zhejiang, and was born in Luogao (now Rugao, Jiangsu). Li Yu was an outstanding writer of operas and novels in the late Ming and early Qing Dynasties. In his works, he expresses tea affairs in many ways. Known as "Oriental Shakespeare", his masterpieces include "Follow the Fate" and "Ten Poems by Li Weng", all of which are precious heritages in China's opera treasure house. He also serves as a new pavilion guest, a world-aware official, a world-aware Taoist, an escort mage and a Li Weng on the lake. Born in the thirty-eighth year of Wanli in Ming Dynasty (16 10), he died in the nineteenth year of Kangxi in Qing Dynasty (1680). My ancestral home is Lanxi, Zhejiang, and I grew up in Rugao, Jiangsu. He was born in a drug dealer's family and had close contact with the citizens since childhood, which had a great influence on his outlook on life in the future. At an early age, I still have the heart to be an official. I didn't get in after several provincial examinations, so I stopped thinking about it. After the Qing army entered the customs, it was not bitter to take shelter from the wind in the mountains for a while. His family is good, but after years of natural and man-made disasters, his family is getting worse and worse, and he gradually leads a life of selling literature. In the eighth year of Shunzhi (165 1), he moved to Hangzhou, which was close to the famous Toshihiko at that time, and most of his opera novels were written at this time. Because of his growing literary fame, he later organized his own troupe to perform specially, which had a considerable impact on the society, and some dignitaries invited him to perform in succession. He also enjoyed it. He often takes his wives and concubines out to play, travels all over the country and enjoys the scenery of Kyushu, making himself a gifted troupe owner. In the first year of Kangxi (1662), he moved from Hangzhou to Jinling (now Nanjing, Jiangsu). Mustard garden is another business of his in Jinling, which is named after the meaning of "mustard meets sumeru". Together with this apartment, there is also a bookstore, which has published many miscellaneous works such as operas and novels, such as the famous Biography of Mustard Garden, which shows that he is a literati with business mind. In his later years, his family moved back to Hangzhou to "buy mountains and hide in Tibet", but his economic situation was much worse than before, and he often asked his friends for help, and finally died in poverty.

Li Yu occupies a place in the history of China opera and even China literature.
