Liu has knowledge of Buddhism, Taoism and Confucianism. "Be familiar with temperament, actuarial mathematics, and look up to Zhan Hou, Dunjia, the Book of Changes and Shao Di Ji Shu." Yuan Junmin Biography said, "Those who know the number of times (skills) cannot leave Liu."

Kublai Khan also praised Liu's "yin and yang skills, which can account for things." If it is harmonious, only I know that others can't get it. " . Mongolia worships immortality, "everything must be called heaven", and distinguishes good from bad through divination.
