There is a Chinese version of Bufferin cold and flu pills here. Good for allergies too. They usually keep them behind the counter and sometimes have told my Chinese wife "don't take those pills!" with big shocked eyes, as if they were similar to the new Krokodil drug out of Russia and will only sell her two boxes at time. Sort of cute in a way. But with me a laowai they sell me as many as I need. They work. Plain and simple. For colds, flu and allergies. You get 8 day time tabs and 4 blue night time ones.
The Chinese, I think, is bai fu lin or ling (I guess ling as there is a small character like ding in there). I can read a couple of the charters and can try to guess at the other one based on the pronunciation. Anyone who can actually speak and read Chinese can clear this up. The first tow characters are 白服 (bai fu) and the 3rd I do not really know. It has kou 口 as the left side radical, then the little "lid" radical (like on top of 安) over top of 丁. There seems to be 8 strokes. Good to have the characters or an old box of the stuff unless your Chinese is really good. I tried it jsut speaking and they looked at me like I had three heads, then took and in the box and muttered back almost exactly in sound what I was saying in the first place. But the pinyin is something like bai fu ling.
Good luck and if you can get this it will help.
