Top: Photo taken in 1986 by Zhou Jiaguo shows doctor Fang Zhirong examining a villager in Liannan Yao Autonomous County, south China's Guangdong Province. Bottom: Photo taken on July 18, 2019 by Zhang Guojun shows doctor Yu Miaochun examining a villager in Chajing Village of Shangmei Town in Wuyishan City, southeast China's Fujian Province. Although the medical services in rural areas have been greatly improved, there is still a great need for long-term dedicated doctors in remote villages. Yu Miaochun, now 42, returned to his hometown as a grassroot doctor at the age of 19 after graduating from a medical school. In 1949 when the People's Republic of China was founded, the Chinese people faced a devastated country that needed to be rebuilt from scratch after decades of warfare and chaos. After decades of unremitting endeavors and dedication by the Chinese people, China has grown to be the world's second largest economy. In 1952, China's GDP was 30 billion U.S. dollars, while in 2018, its GDP reached 13.61 trillion U.S. dollars, an increase of 452.6 times. A group of combo photos give you a glimpse of what Chinese people did decades ago and what they do right now. Undoubtedly, people from all walks of life in China with hard work and wisdom have made contributions to the country's development. (Xinhua)
