It is a more famous cultural street in Beijing Beicheng. There have been many cultural celebrities left in the footprints. It is said that the flag people living in Beicheng at the time were mostly fond of dry or water smoke, and the leaves were packed in cigarette bags. Due to the increasing demand for cigarette bags, one household opened a cigarette bag shop on the street. In addition, the street of the smoke bag is like a smoke bag. The slender street is like a smoke bag pole, the entrance to the east is like a smoke bag mouth, the entrance to the west is folded to the south, leading to the Yinju Bridge, it looks like a smoke bag pot. It is for these two reasons that the name of the Xiejie is really worthy of the name of the "smoking bag".
