Detailed introductions are all detailed in the introduction. Needless to say, the Nanguan was not good several years ago. Only some pictures were seen. This time, I finally had a good time to see the history of Zhongshan State, the Han Tomb in Mancheng and many other cultural relics that I have long missed. Hebei's history is too rich and only part of them are on display. There are few cultural relics in many places. I hope to enrich them. Among many museums in China, Hebei is definitely worth visiting.
