In the early days of reform and opening up, Beijing's antique trading market was once again bustling with activity, especially those dark and damp alleys and backstreet stalls, which became the main places for antique trading. It is full of history and contains countless secrets. The most famous antique trading market is known as the "ghost market". Its name comes from ancient legends and the weird atmosphere here. The ghost market is located in the old part of Beijing, close to an ancient alleyway called "Yin Yang Street". This place seems ordinary during the day, but at dusk, a mysterious atmosphere begins to permeate the place. Many uninformed tourists and collectors like to hunt for treasures here, but only a few know that there is an unfathomable history behind this market.
