The word well-off first came from

If you can't help it, go. Everyone thinks it will hurt. It means well-off. Li Ji Li Yun

The Book of Rites is a compilation of Confucian articles or explanations about the ritual system from the Warring States Period (475 BC-22 BC1year) to the Qin and Han Dynasties (22 BC1year-220 AD), and it is one of the Confucian classics. In the Han Dynasty, Confucian classics were called "Classics", and disciples interpreted "Classics" as "biography" or "recording", hence the name "Book of Rites", that is, the interpretation of "rites". There is more than one author of The Book of Rites, and the time for its completion also follows. Most of the chapters may be the works of Confucius' 72 disciples and their students, as well as other ancient books and records in the pre-Qin period. According to legend, Dade compiled eighty-five articles, which were called "Da Dai Li Ji"; Dai Sheng chose 49 of them, which is called The Rites of Little Wear. At the end of the Eastern Han Dynasty, it was not popular from generation to generation, so Dai Xiao was originally called the Book of Rites, together with Zhou Li and Yi Li as the "Three Rites", with Zheng Xuan as the annotation, and his status rose to "Jing".
