I am annoyed that my master always despises me.

Don't worry, maybe your master thinks highly of you!

According to you, it's not that you can't do well in the skills he taught you. You can be sure that he cultivated you on purpose. He may hate iron for not turning into steel. He wants you to surpass him, or exceed his expectations. Maybe what you did was not up to his benchmark, so he scolded you, but it was also for your own good. If you do things better, he will gradually change his attitude.

Moreover, the old master has a straight temper, but he is generally not bad. It is estimated that there will be insults. My master used to scold me. Finally, when I left him, I didn't cry or drink with me. Old men are all the same. Don't take it to heart, respect them, and you will find that they are actually a very simple and kind old man!
