The word "scrutiny" comes from the poetry creation of poets in the Tang Dynasty.

Jia Dao wrote poems on the donkey's back when visiting friends at night, considering the word "push" or "knock". He accidentally bumped into the ceremonial procession of Han Yu (768~824) and was taken to Han Yuma for interrogation. Jia Dao said he was writing a poem, but the word "push" or "knock" hasn't been decided yet.

Appendix (1), Jia Dao: Li Ning's Seclusion.

Living leisurely here, few neighbors come, and the overgrown path leads to the wilderness.

Birds are freely perched in the trees by the pool, and monks are knocking at the door.

Walking across this bridge, you can see the charming scenery of Ye Yuan, and the feet of clouds seem to be moving on the floating rocks.

I will leave here for a while, but I will come back and retire with my friends on the appointed date.

Appendix (2) Biography of Jia Dao:

Jia Dao, whose name is Lang Xian, is from Fan Yang. He was originally a pagoda without a name. When I came to Du Dong, Luo Yang banned monks from going out in the afternoon, and the island was a self-inflicted disaster. Han Yu pitied him, and because he taught him to be a writer, he went to the pagoda to raise a scholar. Poetry is out of line with the Tao, and although you meet officials and nobles in times of hardship, you are not affectionate. I'm too tired to win the first place. Literati, sit fly slander, belittle the Yangtze River master book. At the beginning of Huichang, a treasurer of Puzhou joined the army and moved, but he did not die. Today, ten volumes of Yangtze River Collection, three volumes of Small Collection and four volumes of poetry collection are compiled.
