I am trying to think of other in-book jianghu wide quotes/sayings like 小李飞刀 例不虚发 from the wuxia novels.
Many characters had Jianghu Titles, but that is boring cos even small potatoes like Jiangnan 7 Freaks had titles.
Golden Lion King, Iron Palm Floats on Water, SWORD OF GOD, GOD OF SWORD Z(h)uo Bufan etc etc, these are all titles/nicknames. Probably North Qiaofeng, South Murong is something similar but that isn't something directly tied to one character.
So, any other quotes/jianghu axioms out there which are not so much titles/nicknames but rather popular sayings about certain attributes of the characters?
