Warmly, Ling welcomed me in a well-trained manner. A bright red sash was across her shoulder. The receptionists, a young man and an older woman, both in black suits, watched curiously yet wordlessly. Ling walked with us to their dormitory, which was right next to the reception at the end of a corridor. She became chatty and could laugh at anything. When she laughed, she looked a little strange with a supernumerary tooth that half covered a regular one.
