Ps: I'm a newbie and I'm not very good at writing, and there was a problem with the mobile office I used for coding in the first two chapters. I couldn't save the revised text. I didn't notice at the time and uploaded the draft as the text. I guess it was very effective in dissuading people from quitting. T_T
