The teahouse at 7am is home to the elderly, who usually go to the fixed teahouse at a fixed time, and sit in a fixed position if conditions permit. Don't look at some old people who go to the tea house alone, but when they sit down, they are "old friends ghosts" around and around, and even the waiters in the tea house are very familiar, and the emotions that accumulate and settle down are flowing between one and two pieces.
