The sky is low in Wu Chu, and the eyes are empty
Pronunciation tiān dī wú chǔ, yǎn kōng wú wù
Interpretation Wu Chu: generally refers to the middle and lower reaches of the Yangtze River. When I first climbed up to the city of Nanjing, I felt that the sky was drooping as I looked away, and there was nothing but the sky. Seeing is also a metaphor for seeing nothing.
Source: "Nian Nujiao: Climbing the Stone City" written by Saduzi of the Yuan Dynasty: "On the Stone City, looking at the sky and the low Wu Chu, there is nothing in my eyes.
