Mr.Sai Mun. A humorous, yet a very responsible teacher. He is definitely one of the best teachers I've ever met in my life. That is to say the way that he teaches his students is one of the appealing part of him; the way he talks too makes every much more fun and smooth to learn. At first I thought I wouldn't get even an "A" in Chemistry, but through practice and motivation from Mr.Sai Mun, it's very much possible. So in the end, Mr.Sai Mun is a great and unforgettable teacher. 11/10 better than the most delicious European fine dining cuisine.
