What were the names of the people who patrolled the streets in the Tang and Song Dynasties?

Patrol in the street is usually patrolled by night watchman or Beijing, similar to the patrol police now. It is called Jin Wuwei because in the Han Dynasty, the emperor's imperial army was called Zhili Jin Wuwei. In the Western Han Dynasty, Zhi Jinwu was in charge of inspecting, forbidding violence, supervising rape and other tasks in the capital, and was as famous as the guards guarding the palace. Su Weidao's poem in Tang Dynasty: "Wu Jin can't help it at night, but the jade leaks and urges each other" borrows the allusions of Han Dynasty. In fact, holding the title of Jin Wu disappeared in the Tang and Song Dynasties, and patrolling the streets is an imperial or police patrol.
