How long does it take to learn eight characters to become a teacher?

Master, you see, which one is broken for life only by eight characters, I will kneel for you! Even blind teachers use the luck limit of 12 palace. Well, it's impossible to do only eight words. Everything is difficult at the beginning, and metaphysics is interlinked. I'm looking at some actual combat cases, and I'm sure I can come out in three to five years.

So far, I dare not speak at the Zhihu for fear of being besieged and rejected (T▽T).
