Tea craftsman Yan Jielong (R) teaches his son Yan Bin how to bake Biluochun tea leaves in Dongshan Town of 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/Han Yuqing)
