The way to mark the tones
汉语的四个声调分别用“ － ／ ∨ ＼”表示。 当一个音节只有一个元音时，声调符号标在元音上，当一个音节的韵母有两个或三个以上元音时，声调符号要标在主要元音上。
The four tones are indicated respectively with the following four tone marks: “－ ／ ∨ ＼” They are marked over the main vowel.
In common speech some syllables are pronounced at a light and short tone. Such tone is called the neutral tone, which is indicated with no mark. e.g.: bàba (father) māma (mother)
