The eight sects of Jianghu are: the first-grade Golden Buddha, the second-grade Taoism, the third-grade Blue Stone, the fourth-grade Red Fire, the fifth-grade Qingyang, the sixth-grade Meiyuan, the seventh-grade Zhumen, and the eighth-grade Orchid.
Collectively known as the Tao of Jianghu, the basis of its existence is mutual assistance, mutual benefit and mutual care in the Jianghu.
This kind of ranking actually doesn't mean much. It can't be said that whoever has a higher level can command other sects. There is no restrictive relationship between them, it's just a false name.
