Why************

It's worth reading. If you don't understand the in-depth terminology written by the author, use the simplest version to make it clearer and easier to understand than what Yu said. Even a novice can understand it. It's better to read it a few times. If you have a minor illness, just use it. It saves money and effort. Everyone can use it.
