After passing by the supermarket gate, I saw many doll machines. The children put coins into the doll machines and played the game of clamping dolls. After the end of the year, some cash was not used up. When I went to the supermarket to buy things and settle accounts, the teller found me some coins. I looked at the coins in my hand and wanted to play with them. At the moment of putting coins, I suddenly felt one thing, that is, the action of putting coins, it is very similar to the feeling of putting coins in a pig piggy bank when I was a child. I can feel the design of a coin piggy bank. The coin opening of this piggy bank borrows the shape of a coin feeder, which makes this product have a little fun in the game. Every coin invested when playing the game is consumed, and every coin invested when saving money is accumulated, so that the two diametrically opposite states of consumption and accumulation coexist, making this piggy bank have a sense of interesting contradiction, coins start our dance academy. Life is like a play. You also have your own way to save money. You might as well share it with us.
