These Taiwan police if they are younger, they know what is this 1 to 4 high school major prior to College.

That physics sheet I give them, doesn't EXIST in the textbook. It was a middle school concept, the people in the high school supposes to done that, or the cram school did, so they memory the end result, NEVER first time ME without the volleyball training, to show up a 20 years later memory, 

"Maybe....I can do this."

I HAVE NO idea, how to make it up THAT.
