Antique songs or poems that express love, such as begging for phoenix.

What is most similar to what you call "Feng Qiu Huang" is the "Four Sorrow Poems" written by Zhang Heng, who was also in the Han Dynasty. This is also an expression of love:

What I think is in Mount Tai, and it is difficult for me to follow it. Look at the east sideways with tears. The beauty gave me Jin Cuodao, so why should I report to Qiong Yao in England? It's a long way to go in Xiu Yuan, so why worry and worry?

My thoughts are in Guilin and I want to go to the depths of Hunan. Looking sideways to the south, tears stained my chest. Beauty gives me a piano and a post. Why should I give you a pair of jade plates? It's a long way to go in Xiu Yuan, so don't worry about it.

My mind is in Hanyang, and I want to go to Hannan from there. Looking at the west sideways, tears hanging on his face. Beauty gives me mink, how can I quote the bright moon pearl? It's a long way to go in Xiu Yuan, so don't worry.

My thoughts are in the wild goose gate, and I want to follow the snow. Tears and towels look sideways at the north. The beautiful woman gave me a brilliant joke, so why should I report the sapphire case? It's a long way to go in Xiu Yuan, so we can't rely on it and sigh. What do you mean by worry and worry?

The earliest sentence to express love should be The Book of Songs. The following songs are the most classic.

Book of Songs. Guan Yu:

Guan Heming's osprey, accompanied by the small continent of the river. A beautiful and virtuous woman is a good spouse of a gentleman.
