Every ten minutes after class, primary school will always take out a blank piece of paper and draw a pattern layout, and then play a defensive game with the front and back tables to commemorate childhood memories.

Introduction to gameplay: If you hit the opponent's chess pieces by bouncing your own chess pieces, you will eat them. If you eat all the flags or attack the opponent's hometown (protruding semicircle), you will win. There can be five obstacles in the middle. The obstacles can be twisted by your hand. By imagining the formation of troops, you can fight in a battlefield.

Benefits: Exercise the flexibility of children's fingers by playing chess pieces, and open the imagination of the brain through the placement of obstacles and chess pieces.

Others: the table can be folded and stored, and there is storage space inside. when not playing, it can also be used as a work table, dining table, etc.
