It is a collection of quotations on cultivation, life, dealing with the world, and the way out of the world, and is a marvellous book that encompasses 5,000 years of Chinese wisdom. As a work rich in the ethical thinking of the Han people, it takes the essence of Confucianism, Taoism and Buddhism, with Confucianism and Taoism as its core, and has the main paths of cultivating oneself, preparing one's family, ruling one's country and pacifying the world; it combines the philosophy of life, the art of living and aesthetic sensibility. It is a beautiful and profound book, but it is also a book to cultivate people's sentiments and refine their will.
