Unlock the door to a private room in a modern self-service mahjong house and switch on the power with a WeChat or Alipay mini-program. Sit down at a premium no-push automatic table that clears, shuffles, and deals by itself, and learn Changsha mahjong by playing real hands.

Read the tiles, learn the rules, and pick up the table talk. Your host sits at the table and coaches you as you play. Along the way, brew tea with a modern tea machine instead of a gaiwan.

Learn how many people here drink tea now: when plain water is not enough, tea is a habit, but there is no time for a full ceremony — a quicker, more modern way to a better cup.
