345 years ago today, on February 12, 1680 (January 13, 1680, the Ming and Qing novelist Li Yu passed away. Li Yu (September 13, 1611 AD, the seventh day of the eighth month of the old calendar-February 12, 1680 AD, the thirteenth day of the first month of the old calendar), was originally named Xianlu, and later renamed Yu, with the word banfan, and called Li Weng. Han nationality, from Jinhua, Zhejiang. A litterateur and dramatist in the late Ming and early Qing Dynasties. At the age of 18, he was a doctoral disciple. He was a scholar in the Ming Dynasty. After entering the Qing Dynasty, he had no intention of becoming an official and engaged in writing and guiding drama performances. Later, he lived in Nanjing, named his residence "Mustard Seed Garden", opened a book shop, compiled and carved maps, and made friends with dignitaries and celebrities in the literary world. He is the author of dramas such as "Phoenix Seeking Phoenix" and "Jade Beagou", novels such as "Meat Futon","Famous Quotes of the World on the Twelve Floors","Silent Drama","Liancheng Wall", and books such as "Leisure Occasion". When Li Yu was born, because his ancestors had been starting a business in Rugao for a long time, he enjoyed a prosperous life since he was born. Later, due to his failure in the imperial examination, Li Yu, who shouldered the important task of making his career prosperous as a family's glory, gave up this pursuit and resolutely changed to the path of "great seclusion in the world". In 1666 (the fifth year of Kangxi) and 1667 (the sixth year of Kangxi), Li Yu received the two concubines, Qiao and Wang. After careful training, Li Yu established a family drama troupe with the two concubines as the pillars. He traveled around the country all year round to entertain high-ranking officials and dignitaries, earning a lot of income. This was also the most satisfying stage of Li Yu's life, and also the most productive period in Li Yu's literary creation. The book "Leisure Love and Occasion" was completed and published during this period. In 1672 and 1673, with the death of Qiao and Wang Ji, the family drama troupe that supported Li Yu's prosperous life also collapsed. Li Yu's life became a difficult situation and often relied on loans to make a living. In 1680, Li Yu disappeared into the world in his youth amid poverty and illness. Speaking of Li Yu, at first, it was almost a conversation between several men, with a little privacy. About how to choose women, the version of "Jin Ping Mei", and so on, they thought they were all secret. But later it was discovered that more and more people liked Li Yu. Not only did men like him, but women also admired him. Can it be said that I like Li Yu almost out of a man's instinct? Because Li Yu is a person who loves life and lives a very artistic life. Moreover, he was able to write his life experience into books artistically, which is what makes him superior to many popular talents. Lin Yutang said when talking about the book "Leisure and Occasion":"Another important part of Li Liweng's works is devoted to the study of the joy of life. It is a pocket guide to the art of life for China, ranging from living rooms and courtyards, interior decoration, and boundary wall separation to a series of arts and delicious food for women's dressing, beauty, and cooking. Ways for the rich and the poor to seek fun, ways to relieve boredom all year round, control of sexual life, and prevention and treatment of diseases..."Li Yu's opera works are stored in the lyrics and lyrics department of" Leisure and Occasion ". He discusses opera literature from six aspects: structure, lyrics, rhythm, guest language, scientific translation, and pattern, and discusses opera performance from five aspects: selection of drama, tone change, teaching, and removal of sets, which has greatly enriched and developed ancient opera theory in our country. In addition to opera theory,"Xian Qing Ou Ji" also covers aspects such as diet, construction, and gardening. In a letter to Gong Zhilu, Minister of Rites, Li Yu said: "There is nothing in the temple to think wisely; if the spring and stone govern, there is nothing to be rich... Use empty words to relax and accumulate a little." It can be seen that this book can reflect his literary and artistic cultivation and interest in life.
