It is from the biography of the Three Kingdoms Shu Shu Gu Fu Zi, which was said by Liu Bei, an ancient master of Shu Han.
Original text? ：
Pei Songzhi, the forerunner of the Annals of the Three Kingdoms and Shu, wrote: "At first, I got sick, my ears were loose, and then I turned to other diseases, almost involuntarily. People die before they are 50 years old, and there are more than 60 years left. Why do they hate and stop hurting themselves? But they will think of your brother. I shot you, saying that the Prime Minister lamented your wisdom, greatly increased his self-cultivation, and was too eager to judge. Why should I be worried? Encourage it, encourage it! Don't do it with small evil, and don't do it with small good. Only virtue and virtue can serve others. Your father's virtue is thin, don't let it work. Reading Han Shu's Book of Rites, observing philosophers and reading Tamia Liu's books are beneficial to people's minds. I heard that the Prime Minister finished writing Shen, Han, Guan Zi and Liu Tao, but he died without delivering them. You can ask Wenda more. "
This is what Liu Bei said in his last testament to his son Liu Chan. The original sentence reads: "Don't feel small evil, don't be ignorant of small good. Only virtue and virtue can serve people. " The purpose is to persuade him to study in Germany and make a difference. Don't stop doing good things because of small things, let alone doing bad things because of small things. Many small good deeds will become great good deeds for the world, while many small evil deeds will be "enough to confuse the country".
