Besides painting, what other categories should be included in the study of China's art history, and what is the relationship between them?

Along with painting, there are sculptures, architecture and arts and crafts, and a very important part of China's ancient art history is religious art, which is often combined with architectural sculptures and paintings.

As for the relationship between them, different periods have different characteristics. Many early paintings were combined with architectural sculpture arts and crafts, such as stone reliefs, brick murals, ceramic paintings and so on. Later, paper and silk paintings became popular, and painting became more independent after the development of mounting technology.

Although you want to introduce it in detail, you don't know how much you know about art history, so you don't know how much you want to read the text. If you want a systematic understanding, you need to borrow A Brief History of China Fine Arts.
