"Heavenly King Gai Di Hu" is an excerpt from "Lin Yuan", which is the slang for bearded people in Northeast China during the liberation of China, and also the slang code for bandits. The slang on the Jianghu originated in the Tang Dynasty, which was originally a code word in business dealings, and then gradually developed because of the rise of illegal trade. Later, it evolved into the language of martial arts people in Jianghu. Slang in Jianghu is also called incision, spring point, inch point, lip point and lip code.
"Heavenly King Gai Di Hu" used to be the second largest language in the world, including not only words, but also daily specific clothes, behaviors, interpersonal relationships, activities of bandits, articles and weapons. It can make it easier for people who can't understand the bandits to communicate, and it can also prevent members from stealing.
