If man does something bad, it will rain. It means: if the sky changes, it will rain. If man does evil, there will be misfortune. "Man's actions bring misfortune, and God's actions bring misfortune" comes from Fan Yin's "Yue Proverbs" in the Qing Dynasty. We all need to have a certain amount of restraint. Once we do something too much, we will be punished by God.

"Yue Proverbs" is the painstaking work of Fan Yin, a Shaoxing scholar in the late Qing Dynasty, who spent several years recording and researching the Yue-Chinese dialects. It is divided into three volumes: "Language", "Names" and "Sounds and Meanings". The second volume " "Sounds and Meanings" also includes "Appendices", including six articles including "On Ya and Popular Characters", as well as two volumes of "Yue Proverbs and Remaining Sayings" that were later added.

"Yue Proverbs" preserves many aphorisms and life proverbs of Yue, covering the customs, ethics, weather, agriculture, and life of Yue. It is very important for the study of the pronunciation and vocabulary of Yue dialect in the middle and late Qing Dynasty. , grammar and Vietnamese culture are of great significance.

The "Yue Proverbs" found today is from the Guyingshanfang collection and the Guangxu Renwu midsummer edition. It is in traditional Chinese vertically arranged, without punctuation, with many variant characters or omitted characters (with missing pens), and some Shaoxing unique characters. Some dialect words use characters that are difficult for ordinary readers to read.

So Professor Hou Youlan took the lead in organizing the annotations of "Yue Proverbs", standardized the font form of the book, unified the style, added annotations to difficult and rare words, and eliminated reading obstacles.
