1.Mahjong tiles can be roughly divided into four types, ‘ 萬’ , ‘ 筒’, ’ 条’, ‘ 字’. For the first three types, each type has 9 different numbers(‘1’ to ‘9’), usually noted by ‘1萬’, ‘2萬’,’1条’,’2条’. If you still get puzzled, just imagine that we express the cards in ‘UNO’ by a number and a Chinese character rather than a colour. For the last type, there are only 7 kinds of tiles, ‘ 東’, ‘ 南’, ‘ 西’, ‘北’, ’白’, ’發’,’中’.
2.‘ 萬 ’ noted by ‘Wx’( x is an integer between ‘1’ to ‘9’), for example (W1,W2,...). Similarly, ‘ 筒 ’ by ‘Tx’, ‘ 条 ’ by ‘Yx’. We name those 7 tiles of the last type by ‘E’,’S’,’W’,’N’,’B’,’F’,’Z’ correspondingly.
3.Here is the priority of Mahjong tiles:
Wx>Tx>Yx>E>S>W>N>B>F>Z
For the same type:
W1>W2>W3>W4>W5>W6>W7>W8>W9
Notice that: For each kind of tile, there are totally four duplicate ones.
