The thought of virtue, merit and speech comes from Zuo Zhuan's Twenty-four Years of "xianggong": "There is virtue in the world, followed by merit, followed by speech. Although it will not be abolished for a long time, this is called immortality. " Lide refers to Lide, that is, to improve moral cultivation and set a moral example for people. Meritorious service means doing good deeds for the people and making great contributions. To make a statement is to write a book with the heart of saving the world.
