The Hong Xiu Zhang is a dangerous organization or criminal group operating in the capital. Several years ago, Lu Sinian happened to rescue Guan Hu from the hands of the Hong Xiu Zhang, an event that ultimately led to Guan Hu becoming the second-in-command of the underground market and taking Lu Sinian and Wei Ping'an under his protection. The organization is implied to be violent and threatening, given that a respected figure like Guan Hu needed rescuing from them. Lu Sinian's encounter with this group was a pivotal moment that set in motion his years of involvement in the underground market.
