This is a sentence from Li Bai's "One of two poems given to my brother Nanping Prefecture":
People at the bottom of Lansheng Valley do not hoe, and the clouds roll up in the sky
The story of Lan Sheng Valley is a reuse of the allusion "Fang Lan is born and has to be hoeed" in the "Three Kingdoms·Shu Zhi·Zhou Qun Zhuan", implying that in the imperial court, the powerful did not tolerate virtuous men and gentlemen. Orchids are compared to wise men and gentlemen. Only in mountains, villages and water countries can a wise man have his own world and a free kingdom. The clouds are free in the sky and can roll up and down at will. The poem is Li Bai's self-portrait, expressing his own aspirations, being sincere and natural, speaking from the heart.
