Thank you, teacher! I will continue to work hard in the future!!! You suggested better directions in practice from time to time in the middle of the lecture, so I am trying to think more about what you said while listening to the lecture and reviewing it, and write my own improvement plan. I am grateful again for giving me a starting point for my thoughts while listening to the lecture, so that I can think about and think about a better direction:) I will visit you with a post after completing each lecture!
