One of my international friends is going to back home, but he never played Chinese Majiang which is part of the quintessence of Chinese culture. So I try to teach them. Finally,they already know how to play Chinese Majiang(actually it is hangzhou Majiang) 我一个外国朋友马上要回国了，但是他从来都没玩过中国麻将，中国麻将是我们国粹的一部分，所以我尝试教他们打中国麻将，终于他们都学会了中国麻将（实际上是杭州麻将）
