Beijing dialect
The literary tones of Beijing dialect tend to be more exaggerated than Standard Chinese. In Standard Chinese, the four tones are high flat, high rising, low dipping, and falling; in Beijing dialect, the first two tones are higher, the third one dips more prominently, and the fourth one falls more. However, toneless syllables are incredibly common in vernacular Beijing dialect and the third tone is realized as a low tone instead of a dipping tone, known as a "half third tone".
