Find the L5master and prepare a vertex table for him.

Find the L4master, prepare a vertex table, and prepare a class training table for him.

The L5master has made comments and also needs a class training table.

In addition, the L5master wants to collect off-duty training information. For example, the number of lines and characters.

Then the L4master is not convinced. He also did one thing, that is, he found out all the "self" in the class training ".

In order to allow students to practice the class training sentence "classroom efficiency is the lifeline of learning ",

Therefore, I purchased a 30-bit mobile phone bag with the class teacher, which was handed over to the L4master by default,

One day, the manager found that the L5master also needs a mobile phone bag to manage the class. There is no way to cut the mobile phone bag in the L4master into the L5master.
