Walking into the ancient city, I found that it was too big, and there was only one broken piece of soil in the building inside. The streets in the city are criss-crossed, and the streets are narrow and deep, like a tortuous war. The temples, government offices, residential areas, handicraft workshops and other houses are all relatively well preserved. Basically, they are dug up from the surface of the shingles by means of reducing the wall and leaving the wall. At that time, the population of 6,500, it is bound to be densely populated here, business travel gathered. In fact, it is more like Pompeii than the Devil City, because most buildings have traces of burning fire. According to archaeologists, the Jiaohe Old City was indeed destroyed by a fire. But even when the sun is shining, I still feel the chill in the baby tomb area. Although no one knows why more than 200 babies have been sleeping here, the bleakness here is self-evident when the sun sets.
