The article is ever-changing and tireless. According to legend, when Wang Anshi, a famous litterateur in the Northern Song Dynasty and one of the "Eight Masters of Tang and Song Dynasties", wrote a sentence "Spring Breeze and Green Jiang Nanan", he repeatedly scrutinized and revised the word "green", from "to", "to" and "to" until he was satisfied with the word "green". According to records, the great Russian writers Lev and Tolstoy's magnum opus War and Peace has been revised seven times, and anna karenine has been written for five years, and only the first part has been revised 20 times. Mr. Fujino, a prose by Lu Xun, a great literary master in China, is less than 4,000 words, but there are more than 160 changes.

This sentence is based on the experience of the ancients and no specific person can be found to say it.

As for the repeatedly scrutinized text, I think it is almost the same, and I can't find the source. Maybe it's because I'm too lazy to change the article
