The famous Zhenyuan Bodyguard Bureau, according to investigation, originated from the revival of Tongzhi. During the period of social turbulence, Zhenyuan Bodyguard Bureau occupied one of the eight bodyguard bureaus with its own strength. In front of the gatekeeper, the gods and beasts were mighty, and the watchtower was high to observe the surroundings. The dart Bureau has restored a lot of operation and life scenes, such as accounts, cabinets, Guangong Hall, kitchen, banquet hall, martial arts training ground, rolling table, etc.
