If I was Mr K Wong,I would very busy.Because Mr K Wong have many job to do.Like to comment on and correct and to conduct a class.I will have so worry,because Mr K Wong do not how to speak and  listen Chinese.

When I was Mr K Wong  I would study Chinese.Because sometimes when the  student have a question ,but the  student not how to speak English to ask me.The  student only know how to  speak  a question .So,if Mr K Wong not know how to listen Chinese,will have so nconvenient.So,I think Mr K Wong should study Chinese.

And I will give homework less to the student.Because I want they have a time to revise.Then,they will not too many pressure.They will to balance happy.
