复制代码One word after the interview, it's difficult. In fact, the interview also gained a lot, and many things that I didn't understand were exposed, which encouraged me to write constantly. Without interviews, these things would basically not be read. The author still enjoyed the interview. After all, he was abused by the gangster and it was still comfortable to communicate with the gangster. The dish is the original sin, the dream still has to be, learn slowly ~ I have received the first offer of life from the headline, Kaisen
I wish everyone can receive the big factory offer ~
