{{Grammar Box}} When you work ''for'' a company, or do other sorts of physical (and even mental) activities for another party, you're likely to use the Chinese preposition 为 (wèi), which is often translated into English as "for," a translation which is often unnatural or unnecessary, depending on the particular phrase. The super common Mao-era phrase, 为人民服务 ("serve the people"), doesn't need the word "for" in English, for example. Don't confuse this preposition with [[Expressing purpose with "weile"|为了]], which is a bit different. == Structure ==
