How are ancient songs divided? What's the difference between what we use now and what we used in ancient times?

The tones of ancient Chinese can be divided into four tones: flat, rising, going and entering. "Ping" refers to the flat tone among the four tones, including Yin Ping and Yang Ping. "Wrong" refers to the mistake of four tones, including the upper, lower and middle tones.

According to tradition, a flat tone is a flat tone, a rising tone is a rising tone, a falling tone is a falling tone, and an entering tone is a short tone. In the Ming Dynasty, jade melody was released.

Flat voice, flat road, mo di ang,

The voice above shouted fiercely and strongly:

It's a long way to go, Xiu Yuan,

The urgent voice is short and urgent.

Simply put, the key to equality is "inequality is equality".

-Levels and levels in modern Chinese:

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 consonant in modern Chinese.

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).
