Top: File photo taken in 1958 by Li Deyi shows staff members processing newly-picked tea leaves at an agricultural cooperative in Enshi, central China's Hubei Province. Bottom: Photo taken on April 11, 2018 by Zhang Guojun shows Jiang Yuanxun (2nd R), an inheritor of black tea production, instructing a farmer in processing black tea at Tongmu Village in Wuyishan, southeast China's Fujian Province. With the development of large-scale and industrialized tea production, more and more farmers in Tongmu Village have benefited from the tea planting and processing, which has become a pillar industry to increase local farmers' income. 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)
