Firstly, it is free, and secondly, the most important thing is that the exhibits are loaded with the local cultural heritage of Zhengzhou, including the history of Zhengzhou, the replacement of the princes, and various utensils from archaeological excavations to study the life and survival of ancestors. The authenticity of historical existence and its truth are engraved in bronze wares. My favorite is the wine source, which used to be called the noble, and all kinds of cold weapons left by war. Looking at the unearthed cultural relics, my heart is always heavy, not only because of the deposited relics of the ancestors, but also because of the technical ability and wisdom of the ancestors. We should all read history and learn from it.
