This sentence comes from "Luo Shen Fu": "Hugh Xun flies away, wandering like a god, taking a little step and dusty socks. Unstable is dangerous, and dangerous is safe. Enter a difficult period, if you go, if you return. Into liquid sperm, smooth and beautiful. If you don't spit, you will be angry. Huarong is graceful, which makes me forget the new year. "
The original intention is to describe Luo Shen's lithe posture, floating on the water waves and walking slowly. Jin Yong described it as a kind of martial arts in "Eight Dragons", in which "Hugh Xun flies around like a god" and "impermanence means impermanence, and if it is dangerous, it is safe. If you enter a difficult period, if you go back "can be used as the annotation of this kind of martial arts." "
Here socks should refer to belts. Tube top (commonly known as Chinese-style chest covering) is also the name of ancient women's clothing belt.
