BEIJING -- Every morning, as many as 20,000 people flock to Tiananmen Square to join the vast queues of pilgrims, often stretching a kilometre long, at the entrance to the tomb of Mao Zedong. They stand for an hour or more, in blazing sun or winter cold, waiting patiently to pay their respects to the Great Helmsman. They place flowers at the foot of a Mao statue. They gaze reverentially at the chairman's crystal coffin, often bowing to the waxy corpse inside.
As far as I know, Mao is a vreated to simulate Communist China and supposedly named after it's creator, Mao Zidong. The laws(rules) of the game aren't always certain and players get penalized for not following them. After playing your last card, you must call Mao and it must be the last thing you say at the end of your turn. 2  You can not play off suit unless the number you play matches the number on top of the discard pile.
