Right: Photo taken on June 26, 2019 by Zhu Zheng shows farmer Cui Xinjian displaying how to adjust temperature and humidity with a mobile app at a greenhouse in Cuixi Village of Shouguang. Shouguang, now a county-level city, has become a major vegetable growing base and well-known in China since more farmers joined greenhouse vegetable growing business in the 1990s. The city has been cited as a modern agricultural demonstration zone and has provided integrated vegetable growing solutions to more than 20 provincial-level regions. 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)
