The problem of temperament is not much of importance in Philosophical discussion compared to subjects such as liqi and Xingli. However, temperament is of great importance in practical study theory. "The reason people study is because they want to change their temper." the scholars said. The theory of change in temperament in neo-Confucianism is pursued in two directions. The first is to purify the temperament in a clear state. The second is to overcome the bias of temperament and lead it to a state of the middle path. The former is the study that purifies the murky water and turn it to a clear state, as the bead in it is brilliantly revealed. The latter is the study of maintaining without bias toward the path of nature itself. While the ultimate purpose of temperament change is to realize bright nature intact without obstruction of temperament, it goes through two processes specifically. It is to maximize intellectual and practical ability and overcome bias in inclination and character. The purification of temperament and the realization of Zhong are in sync with the orientation of the theory of temperament change.
