It was at a teahouse at the foot of the Dagu Glacier, Sichuan Province, that I met Gen Deng Zha Xi, an 82-year-old inheritor of Si Bo le, a local intangible cultural heritage. He was sitting by the window, with his left hand fingering a string of Buddhist prayer beads and his right hand revolving a prayer wheel. Wearing a quiet expression and gazing outside the window, the old man seemed to be thinking about something. [Photo by You Zixuan/China.org.cn]
