Jinsha is a special place that grown-ups like to visit to learn about history. It's like a big playground for scientists who want to check out things that people used a long time ago.
This place is in China and it is very old. People who lived there a long time ago used to make things out of bronze and jade. Bronze is a pretty, brownish metal that looks like gold, and jade is a greenish stone that people think is very valuable.
When the scientists go to Jinsha, they dig in the ground to find things that the people used a long time ago. They find all sorts of things like pots, knives, jewelry, and even skeletons!
The scientists then put all the things they find in a special room with glass cases where visitors can see them. People who go there can see all the cool things that people used to use a long time ago. It's like going back in time to see how people used to live.
