In 1978, he went to Romania to study poultry breeding. After returning to China, he held a national training course for poultry breeding experts. President of the Poultry Quality Traits Research Association, special reviewer of the National Invention Award, and member of the World Poultry Research Association. He has participated in and hosted Shandan Army Horse, Beijing White Chicken, and Beijing Yellow Chicken. Jingxing Broiler 100, 101, 102, Palace Broiler and other varieties and strains are selected and bred. It also participates in the breeding of Inner Mongolian sheep, Chinese rabbits and meat rabbits, and also breeds and promotes Jingchuan White Chicken. In particular, the dw gene was introduced into high-quality broilers, and the distinctive Chinese bantam D1 line (recessive white feathers), D2, D3, D4 lines (yellow feathers), D5 lines (hemp feathers), and D6 lines (black feathers) were selected and ), Dg (bantam oil chicken), they all contain the dw gene, which can save more than 20% of feed, have high reproductive rate, strong disease resistance, and the economic benefits of breeder chickens can be increased by more than 40%. These strains are unique to my country. As supporting maternal lines, it is an innovative project to improve my country's local fine breed chickens and protect chicken breed resources. He participated in the establishment of my country's first factory chicken farm - Hongxing Chicken Farm and Original Breed Chicken Farm, and pioneered and successfully tested the "double selection breeding method". It is still the world's most advanced breeding method and will double the efficiency in conventional breeding.
