Primary school pupils learn to pick tea leaves at the Dingxin tea garden on the Baixiang Mountain in Banan District of Chongqing, southwest China, April 25, 2019. After graduating from a U.S.-based college in 2014, Zhang Lu returned to her hometown in Chongqing to manage her family's Dingxin tea garden. After a few years of exploration, Zhang developed a model of managing the tea garden covering an area of about 4,000 mu (266.67 hectares). Apart from growing and selling tea leaves in collaboration with cooperatives, Zhang also beefed up efforts to develop tea-picking and tea-making tourism. Now her tea garden has received more than 300,000 visits, an important source for Zhang and households surrounding her tea garden to boost their incomes. (Xinhua/Wang Quanchao)
