I called my mama at 10 am. She told me that she felt better after she took the drop last night. She also it is too hot in Hubei. So i decide to buy an air-condition for them.

        In the morning, a boy asked me how to study when i was reading. He wants to find a part time job and study after he is off duty. He wants to sit for the university entrance examination. He said he may slowly improve his knowledge by this way.  Frist, what he thinks is very good. In our society, it is one of the best ways to change one's life by university entrance examination. But the way what he is going to adopt is not available. Because anyone has lackness in some degree. In high school, you fail under the condition with high pressure. And there is not a reference when you study, so you don't know your ability. So i don't agree with him. My advice is, "you go back your high school and prepare to study one year, which may let you come to one university."

        I continue to amend my paper tomorrow and read books about data structure.
