If you want to learn early technology, how many days can you learn it?

If you want to learn breakfast skills, you can learn them in a few days, depending on your understanding ability and the difficulty of breakfast. Generally speaking, you can learn it completely in ten days and a half months if you are early. It's more difficult, for example, the breakfast time in a high-end tea restaurant may be longer, but as long as you study hard, there is nothing you can't learn.
