1959 graduated from zhalantun forestry school, and now he is the chief and researcher of the science and technology department of the municipal forestry research institute, the representative of the seventh national people's congress of the autonomous region, the representative of the fourth party congress of the autonomous region and the representative of the eighth national people's congress. 1984 was awarded the title of "National Advanced Worker in Agroforestry Science and Technology Extension" by the State Agriculture Commission, Science and Technology Commission, Ministry of Agriculture, Animal Husbandry and Fisheries and Ministry of Forestry, 1986, 1989 was awarded the title of "Model Worker" in the first phase of "Three North" Shelterbelt, autonomous region 1989.

1965- 198 1 cooperated with China academy of forestry and Yanbei, Shanxi province to study the project of "transformation and high-yield technology of Xiaoyang forest" and won the first prize of scientific and technological achievements of Shanxi provincial government. 1978 participated in the project "farmland shelterbelt construction technology and its benefits" and won the national science conference award. 1980 won the second prize of scientific and technological achievements in the autonomous region. 1984 presided over the project "Study on Afforestation Technology in Arid Loess Hilly Area", and won the second prize of national scientific and technological progress and the first prize of autonomous region scientific and technological progress. Based on Chengzi Township in Songshan District, this study carried out unified planning, comprehensive management of small watersheds, combination of arbor, shrub and grass, mixed needles and broadleaves, and grid interspersed. The coverage rate of forest and grass increased from 2.9% to 33.8%, and the grain yield per mu increased from 20 kg to 1.8 1 kg in 0987, realizing forest enrichment. It is measured that the amount of soil erosion has decreased by 98%. This scientific research achievement has been popularized in six counties of the city.

1In February, 1988, at the invitation of the International Association for Soil and Water Conservation, he went to the United States to attend the annual academic conference held in New Orleans, Louisiana. The paper "Building Soil and Water Conservation Forests in Arid Loess Hilly Areas" read by him at the conference attracted wide attention. 1February, 990, he was invited to attend an academic conference in the United States again.
