Neijing Tu is a picture that helps people understand traditional Chinese medicine. It's like a map that shows how different parts of our body are related to each other.
For example, in the Neijing Tu, there are different colored lines that connect different parts of our body. These lines show how our organs, like our heart and lungs, work together with other parts of our body to keep us healthy.
The picture also shows little symbols that represent different things, like animals or shapes. These symbols help people remember which parts of the body are related to which organs.
Overall, the Neijing Tu is a helpful tool that traditional Chinese medicine doctors use to understand how our body works and how different parts are connected to each other.
