1, rabbit's phonetic tone: tù zi. In which "Zi" is bass, which seems to be short-pitched, and the key value is 1 degree.

2, the rules of pronunciation of light tone:

After leveling, the tone falls in my mind, which seems to be a shorter tone, with a value of 2 degrees;

After rising, the tone falls in the middle of the head, which seems to be a shorter tone (but slightly different from that after falling), with a tone value of 3 degrees;

Read a semi-Gao Pingtiao (or a slightly rising tone) after rising, like a light and short flat tone, with a tone value of 4 degrees;

After the tone is removed, the intonation is low and falls, like a short tone removal, and the value is adjusted to 1 degree.

In short: when the current word is the upper tone, the pitch of the light tone word is higher; When the current word is in other tones, the pitch of the light tone is lower. The light tone after leveling, rising tone and falling tone is falling tone, and the light tone after rising tone is flat tone or not obvious rising tone.
