He is the author of the book "The Fine Solution of Six Plum Blossoms". The book truly records its own prediction examples. In order to help beginners, the source of each sentence is clearly marked in the book, which is very popular with students.

Teacher Jia Shuangping has been studying Yi-ology for more than ten years. She has studied Huang Jian's Plum Blossom Yi Shu and Liu Yao's Liu Changming. She learned from the past and learned from the past, and dared to innovate boldly in experimental practice, absorbing the strengths of many schools. She combined the plum blossom easy number with six hexagrams and achieved good results in practice. Up to now, many people in the field of Yi studies still follow the old conservative concept, and if they know a little, they regard it as a "trick" and keep it secret. Ms. Jia Shuangping believes that learning easy is never a trick. The key is to grasp the fundamental principle and thinking mode of a prediction model from the perspective of easy, and then dare to use it boldly and flexibly in practice, which will get twice the result with half the effort.
