[殺價shājià: bargain 買雨衣mǎi yǔyī：buy raincoats]
Learning Mandarin is the best policy to bargain in Taiwan!
On such a rainy day, one of my students went to Family Mart to try out his bargaining task right away after our morning class.
What surprised me is that he actually made it. He successfully bought two raincoats with a discount! Oh...Taiwanese are really friendly to foreigners who can speak Chinese.
