Women of Bai ethnic group sing a welcoming song for guests at the door of a tea house at the Suoziqiu Village of Mahekou Township in Sangzhi County of Zhangjiajie City, central China's Hunan Province, Oct. 11, 2018. People of the Bai ethnic group here still follow the welcoming tradition of their immigrated ancestors to offer "Three Bowls of Tea" to guests. The first bowl of tea is Bitter Tea, implying the miserable immigrating tour. The second is Sweet Tea with the meaning of happiness of successful immigration. The third is Reunion Tea, which stands for a peaceful settlement. (Xinhua/Jin Linpeng)
