Yan Shu Huan Xi Sha helped me point out its level and rhythm.

1, flat:

A new song and a glass of wine, the weather was old last year.

Pingping Pingping Pingping Pingping Pingping Pingping Pingping Pingping Pingping Pingping Pingping Pingping Pingping Pingping.

When will the sunset come back?

Flat and light.

There's nothing to do, bloom's flowers fall, and it's like deja vu when Yan returns.

Flat flat flat flat flat flat flat flat flat flat flat flat flat flat flat flat flat flat flat flat flat.

Wandering alone in the small garden, fragrant path.

Pingping Pingping Pingping Pingping Pingping Pingping.

In other words, the paradigm in the tune of Huanxisha is like this (in which the word "zhong" means that the words used here are even and even. )

It's plain, plain, plain, plain.

The middle is flat, and the middle is flat. General, general, general.

2, rhyme:

Cup, table, back, come, linger (even water and ten ashes)
