<human>:  What are the basic rules to playing Mahjong?
<bot>: 
1. Choose the seat position you want to take.
2. Each player at the table receives 13 tiles(a mixture of bamboo, circles, and characters) to create a winning hand.
3. The goal of the game is to create four sets and one pair of matching tiles.
4. The four sets can be either pungs (three of a kind), Chows (three in a consecutive sequence) or Kongs (four of a kind).
5. Once the entire hand has been set up, the remaining two tiles are then discarded.
6. After the discard, turns proceed in a counter-clockwise direction.
7. You may either draw tiles from the wall or your opponents’ discarded tiles.
8. For each turn, you must have one discard.
9. The game ends when one of the players has a winning hand and reveals it to the other players.
