1. "I will search up and down" comes from the 97th sentence of "Li Sao" written by Qu Yuan. It talks about Qu Yuan's unremitting pursuit of political ideals. Later, people in the world used it to describe people's persistence and tenacity.

2. "Li Sao" (excerpt): If you want to keep this spirit as trivial as possible, the sun will fade and it will become dusk. I ordered Xihe to take care of the festival, and look forward to the concubine without any pressure. The road is long and far away, I will search up and down. The remaining horses are drinking in the salty pond, and the remaining bridles are like hibiscus.

3. Fold the wood to brush against the sun, and chat leisurely to look at the sheep.

4. Vernacular translation: I originally wanted to stay in Lingsuo for a while, but the sunset was already dark. I ordered Xi He to stop his whip and move slowly, and not to let the sun approach the Kuangxi Mountain. The road ahead is long and far, and I will pursue my ideal up and down. Let my horse drink from the salty pond, and tie its reins to the hibiscus tree. If I fold the branches to block the sun, I can wander leisurely for the time being.
