In 1979, China and the United States formally established diplomatic relations. Li Jingzhong, a doctor of science and engineering who graduated from the Massachusetts Institute of Technology, found the opportunity to return to China. Over the years, Li Jingzhong, who appeared to be a Chinese American, had been replaced by a young man of the same name in the 21st century. Therefore, after the concerted efforts of concerned people at home and abroad, Li Jingzhong finally took his parents on the return flight.
After returning to China, Li Jingzhong started from the picture tube and made China great again step by step.
