Tea craftsman Yan Jielong processes Biluochun tea leaves in Dongshan Town, Wuzhong District in Suzhou, east China's Jiangsu Province, March 20, 2018. The production of Biluochun tea leaves follows a set of procedures that are handed down by generations of tea craftsmen. Yan Jielong started to learn tea-making at the age of 16. A few years ago, his son Yan Bin also quitted from his previous job and focused on learning tea-making. In addition, Yan Bin has been using the social network to promote tea culture. As inheritors of the tea-making craftsmanship, Yan Jielong and Yan Bin hope they may someday open a school to share the know-hows with the younger generation. (Xinhua/Ji Chunpeng)
