How did Xiao Ming die?

Those who are hated by students, killed by teachers, and choked to death by countless questions. He often turns the ink on the shaft and then calculates the numbers on the shaft; He goes out to travel when he has nothing to do, and often entangles in two travel agencies; He went out to buy things without looking at the quality, and first listed an equation group to calculate the profit of the merchant; He has a good friend named Xiaogang, so they just wander in A and B, watching each other meet again and again, silently recording the time and calculating each other's speed.

There is no such thing in a miserable life. How can you not die early? (Calculate funeral expenses ...)

Hope to adopt ~
