In the northwestern part of Yunnan, there is such an ancient town with a long history. It was once praised by foreign tourists in modern times. It was once known at home and abroad. This is the ancient town of Dukezong in Shangri-La.  The town on the ancient tea-and-horse road was destroyed one day in 2014 due to a fire. Only the broken wall remains. Fortunately, in order to make up for this, the local people formed a new Dukezong ancient city after the ancient city was burned and renovated. This ancient city is the oldest and youngest in China. It seems that Shangri-La Dukezong has become a place that you can’t miss out on. Shangri-La’s ancient city of Dukezong, which was once popular, is now very weak, but in this case, it has brought a real clean travel place for tourists, and really makes busy people in the bustling city seek their own clean place here. Is this not a good thing?
