There are poems like words in the Book of Songs.

Lu Fen:

Follow his grave and cut its pieces; If you don't see a gentleman, you will be hungry.

Cut down his grave; See a gentleman, don't give up.

Squid tail destroyed, royal family destroyed; Although destroyed, parents are Confucius.

There are dead birds in the wild;

There are dead birds in the wild, but white grass can cover them. A woman fell in love with spring, and Ji seduced her.

There is a park in the forest and a dead deer in the wild. White grass is pure, and there are women like jade.

Bai Zhou:

Pan He Bai Zhou, also Pan Qiliu. If you are worried, if you have hidden worries.

Yan Yan:

Swallows are flying in the sky with uneven wings. My sister married in the country today. Looking forward to it, tears are pouring down!

In the Book of Songs, there is the word "Ru" in the above four poems.
