I think, there are not a few Chinese people who don't know the Niangziguan because it is a world. Its existing Guancheng was built in the Ming Dynasty, and it is opposite to the well in the well. It is a military heavy land. It is known as the ninth gate of the Great Wall. It is very dangerous and is a battleground for the dynasties. The driver heard that we went to Niangziguan, and I kindly reminded everyone to add more clothes, saying that the wind is big and it will be cold. After a long journey in the afternoon, I finally came to this place, and I was about to turn to the sun, and hurry up to see. Just entering the door, I saw a cute dog, who kept guarding the door, and felt like a guardian guard. We shot it, it didn't run, and it worked quite well.
