Mawangdui Silk Texts are really old pieces of paper that people in China made a long, long time ago. They were found in a place called Mawangdui, which is like a big grave or tomb where people were buried a really, really long time ago.
The Mawangdui Silk Texts are special because they have writing on them that tells us a lot about how people in China lived a long time ago. The writing is not in our normal letters, it is in a kind of squiggly line that only people who studied it for a very long time can understand.
These special papers were kept really safe in a big rock that was the grave, but they were still very old when people found them. So, it was really important to take care of them carefully so that they wouldn't break.
Now, people who know how to read the squiggly lines on the Mawangdui Silk Texts look at them a lot to see what they say. They tell us about ancient Chinese medicine, stories that people used to tell, and even how people in China used to make maps! It's like looking into a really old book and learning about grandma and grandpa's time!
