Zhang Jianhua's personality career.

1987 After graduating from Medical University, he was assigned to the internal medicine department of Xishan Mining Bureau Staff Hospital. Because it was "Hainan fever" at that time, he worked as a business manager in the foreign trade department of Hainan Yaxi Industrial Development Co., Ltd. (Sanya), and then moved to Guangzhou as a business representative of Hong Kong Jiajia Foreign Firm, and made his first oxalic acid business. At that time, the goods were purchased from the manufacturer at 3500 yuan/ton, CIF Hong Kong price 1200. Profit.

1990 was admitted to China Institute of Radiation Protection to study the damage of radiation to human body and study for a master's degree. I learned in my study that after the atomic bombs exploded in Hiroshima and Nagasaki, Japan, the organ most damaged by radiation was the ovary, which led to infertility. Twenty or thirty years later, osteoporosis, femoral head necrosis and fracture will occur. The reason is that the content of estrogen secreted in the body is low after ovarian injury, which leads to calcium deposition. The World Conservation Committee (ICRP) has been trying to find a way to treat estrogen deficiency caused by ovarian injury. Scientists all over the world have discovered human placenta, which is a traditional Chinese medicine used in China for more than 2000 years. During the research period, the Chernobyl nuclear power plant in the Soviet Union exploded. At that time, Ukrainian scientists rushed to Zhongfu Hospital to extract the active factors of human placenta with us and transported them to the Soviet Union to offset the harm of radiation to women's bodies, which left a deep impression on human placenta.

1992, I read with great interest Guangming Daily's reference to Dalian's "North Port". Seeing the advertisement of Dalian municipal government for talents, I took this newspaper to Dalian to apply. Employed by Xigang District Commercial Administration Bureau of Dalian, ready to send to Fiji, a Pacific island country, to carry out foreign trade business.
