1. Nanguan Street is located in the south wall of Zhengzhou and is an ancient street with a long history. This used to be the bustling business district of Zhengzhou. Its narrow and winding streets give people a quaint feeling, as if reminiscent of wars and military manufacturing in history. Therefore, people are used to calling this street "Gun Street".
2. Nanguan Street was the gathering place of firearms workshops in Ming and Qing Dynasties, and it was the place where all kinds of firearms were produced and sold, including shell casings and barrels. The manufacture and use of these firearms require extremely high technology and experience, so the craftsmen here are very skilled. At the same time, firearms often exploded at that time, so this street was also called "Gun Street".
To sum up the above two points, Nanguan Street is called "Gun Street" on the one hand because of its historical origin and military manufacturing characteristics, and on the other hand, it is related to the gathering of firearms workshops here in the Ming and Qing Dynasties.
