Oh, I haven't written anything for a long time. I guess many of you have visited my blog only to get disappointed in it not having any new post. I am sorry for that.
I have been very busy since the new school year started in April. I am in charge of the third graders of my school. They are studying harder to pass their entrance examinations at the end of this year. I am also busy helping them.
And I have another problem: my knee! It suddenly began to hurt so much that I couldn't walk. I went to see a doctor, and he examined my knee. He told me it had some water (sorry, I don't know the correct English word for it) and he got rid of it. Now I can walk, but my knee sometimes hurts. I had never thought of how important the function of one's knee is.
Readers, just wait for a while. I will start to write again pretty soon.
