Pingsheng and Cuosheng generally refer to the rhythm of poetry. Flat tone is an attempt to dualize the four tones. Four tones are four tones in ancient Chinese. Tone refers to the level, fluctuation and length of sound.

On the basis of four tones, the flat tone is summarized through incomplete induction. Flat refers to straight, flat refers to twists and turns. In ancient times, it was raised, lowered, lowered, and the rest was flat. Since Zhou Deqing in Yuan Dynasty, Yin and Yang have been equally divided, with flat tone, flat tone, rising tone, falling tone and canceling tone. From ancient times to the present, the levels of balance are unbalanced, and the dispute between level balance and informal level balance is an eternal topic.

In modern Chinese, there are four tones: even tone, rising tone, rising tone and falling tone.

In modern Chinese, the tones of ancient "Pingsheng" can be divided into Yin Pingping and Yang Pingping, namely the so-called first and second tones.

In modern Chinese, the tone of the ancient "Shang Sheng" is partly disyllabic and partly Shang Sheng. Shangsheng is the third sound of modern Chinese Pinyin.

In modern Chinese, the tone of "Qusheng" in ancient times is still the fourth tone.

The ancient "Rusheng" tone no longer exists in modern Chinese. It has become a flat tone, a rising tone, a falling tone.

The four tones of modern Chinese are Yin Ping (Shang Sheng), Yang Ping (Second Tone), Shang Sheng (Third Tone) and De Sheng (Fourth Tone).

For example:

mother

dead

horse

abuse

(level)

(Yang Ping)

(first sound)

(silent)

In short, among the four tones in modern Chinese, the first and second tones are flat tones; The third and fourth sounds are ligatures.
