Top: File photo taken in 1978 shows workers making daily-use porcelain wares at a ceramic factory in Jingdezhen, east China's Jiangxi Province. Bottom: Photo taken on July 26, 2019 by Wan Xiang shows Huang Xu, a staff member of a ceramic 3D printing experience center, making porcelain vases via 3D printing facilities at Taoxichuan, a renovated production area in Jingdezhen of Jiangxi. Boasting varied porcelain products ranging from porcelain wares of everyday use to fine and special ceramics, Jingdezhen has been committed to developing ceramic industrial chains in sync with the growth of innovation and cultural chains. In 2017, the value of the city's porcelain industry reached 37.2 billion yuan (about 5.25 billion U.S. dollars), of which the revenue of porcelain pieces produced with high-tech methods and for artistic display accounted for nearly half the total. 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)
