Here is the capital of my great summer dynasty. There is a very domineering name here - Tongwan City. The meaning of a unified city. Tongwan City is the only ancient city of the northern minority nationality that has been preserved to the present. The white walls of the site, the horse-faced ridges, the towering turrets, the unique structure of the "Taiwan secret room" and the majestic palace building ruins clearly evoke the meaning of "unifying the world, the kingdom of the country" The outline and scale of the capital city of Daxia. There are many birds on the wall that have been flying, seemingly guarding the land. 1600 has passed, and the walls here are still standing. I am here, although I am not there, but I can still feel the mighty power of my great summer country. The white walls are mixed with grass and sand with glutinous rice juice, and a white city in the golden desert is very spectacular. There are many similar deep pits in the city of Tuanwan. It is excavated by archaeologists during this archaeological period. Everyone must pay attention to the safety under their feet. It is very painful to accidentally fall. . . Standing here to see the endless grassland in the distance, an old building can be a distant view of the old man and the birds. But seeing these ruins, it is not difficult to imagine how prosperous and prosperous it was 1600 years ago.
