Is it possible to learn about learning sweet points?

1 is a student at a mask shop, 2 is a school at a school
You're a professional tea master, I'm a non-construction student,
In fact, the main reason for the students is to work, use the work outside the time to study, naturally the physics students will have a lot of time to work on the day, and the work is always available. It's a single item that I like to study, and the consumption time is very long.
