T–V distinction
Although Chinese speakers make a clear distinction between Standard Chinese and the Beijing dialect, there are aspects of Beijing dialect that have made it into the official standard. Standard Chinese has a T–V distinction between the polite and informal "you" that comes from the Beijing dialect, although its use is quite diminished in daily speech. It also distinguishes between ""zánmen" ("we" including the listener) and "wǒmen"" ("we" not including the listener). In practice, neither distinction is commonly used by most Chinese, at least outside the Beijing area.
