Mr Li made good preparations for his lessons and was strict with us,ever we made mistakes in our homework,he would ask us to correct and do it again. I used to be poor in physics. Mr Li often helped me with my lessons very ks to his help and hard work,I have made good progress and caught up with the a retired teacher,he's still working hard for our educational cause(教育事業).
