Shop introduction: Sideng Sifang Street has the most commercial atmosphere. The buildings that reflect the Tea Horse Road market are the commercial buildings densely scattered around the street and on both sides of the lanes. It is the guarantee that the entire street will last for thousands of years. To put it simply, the front shop and back horse shop means that the houses facing the street and lanes are opened into shops, which are mainly used for business or renting out to others. The houses and courtyards behind are opened into horse shops for accommodation and accommodation for caravans and merchants traveling from north to south. Stocking and storing horses. This kind of commercial layout is all around Sifang Street and on both sides of the three ancient lanes and has been basically preserved intact, making it the only surviving town of the Tea Horse Road Market.
