If you go to walmart, you can easily find it, it is called plumber gel ( I forget the exact name, about 7$ a big bottle). Pour it into sink and wait for 15-30 minutes to flush with hot water. Done!
second一下胖老师。见过n个类似的例子,比如说经济形势不好,当年没花光的钱本来 是可以转的,会突然被学校用各种借口挪走。 美国人有个观点:花钱少是因为你不需要,use it or lose it。更悲催的是不但把你 含辛茹苦省下来的钱贴补给了大手大脚的pi,还在考核时认为你花钱少是工作不够努力 的表现。

看一个电视节目介绍过一个简单的招:Pour about a 1/4 cup of baking soda in and then a cup of vinegar on top of it. 也能起到清洁下水管道的作用。
