Zhong Minghua, a fruit technician from the cattle breeding and marketing cooperative of Xiuyan County, updated and rejuvenated Laoshan eucalyptus trees in guiding the production of mountain ridges, and achieved a significant increase in yield. There are 202,000 Hawthorn trees in the Cow Cattle Commune, including 14,000 tree species and 4,000 old trees for more than 40 years. During the ten years of turmoil, the yield of the mountains has hovered around 100,000 kilograms. After Ming Minghua served as a technician, he summed up a complete set of technical measures for increasing production, so that the production of hawthorn increased year by year. In 1979 it was 150,000 kilograms, in 1980 it was 200,000 kilograms, in 1981 it was 270,000 kilograms, and in 1982 it was more than 300,000 kilograms.
