Cui Hao
Late in 414, Emperor Mingyuan began to have his official Cui Hao (the son of his key advisor Cui Hong (崔宏)) teach him the ancient texts of "I Ching" and "Hong Fan" (洪範) – both mystical texts. He also often asked Cui Hao to make predictions based on those texts, which often came true. Cui Hao therefore became increasingly trusted and consulted by Emperor Mingyuan for important decisions.
