Nice to meet you. I have a daughter and a son. They are both students. One is a middle school student, the other one is a primary school student. As a father, I want to be a role model by studying with them. I'm also a teacher in middle school. In my free time, such as during the summer holidays, I'm very glad to help someone that needs help in Chinese or chemistry. You are welcome. If you are free or need help, why don't you call me. My WeChat is sdzzcz768. See you!
