The issue of life and death is a vital question that no philosophers of life can avoid. The philosophers of mind in the Ming Dynasty, such as Wang Yang-ming, Wang Long-xi and Luo Ru-fang, founded their theories on the Pre-Qin Confucians' wisdom of life and death, assimilated Buddhist and Taoist ideas about life and death as well as inherited and advanced Zhang Zai's ideas of life and death in his theory of Qi from the Song Dynasty. All the above ideas of different sources formed the wisdom of life and death unique to the Confucian school of mind in the Ming Dynasty. Their wisdom about life and death took ”conscience and mind” as the subject. ”knowledge about the course of day and night” as the theme and ”transcending life and death in the practice of spiritual cultivation” as the goal, forming a line of beautiful sights in the long river of traditional Chinese philosophy of life.
