The oldest commercial street in Beijing is Dasilan, the most famous and peculiar prosperous street. Its history can be traced back to five hundred and eighty years ago when the Emperor ordered to build fences to prevent thieves from hiding. The fences built here were quite peculiar and kept for a long time. Later, Big Fences became the name of this street: Dashilan.
Dashilan is situated on south of Tiananmen Square, west of Qianmen Dajie, where many century-old shops and Restaurant stand. You can buy some traditional handcrafts as well. Note that bargaining is always needed.
