Hello ~! I would like to ask you a question: Do the patents on scientific research achievements of university teachers belong to teachers or schools? What is the legal basis?

Strictly speaking, because the research content of college teachers is uncertain, any achievements he makes can belong to the service invention and the school, especially the research direction is the same.

But generally speaking, unless it is the direct result of the project, it is not a big problem for other inventions you like to make to apply for patents as non-service inventions, and ordinary schools will not delve into them.
