To tell the truth, the child has a business mind at such a young age. If he is well trained, he will succeed. This is not good at this stage. After all, children have no mature thinking. This kind of behavior will lead children to take money as the standard, ignore the friendship between classmates, and go astray ideologically. He should be taught slowly that this stage belongs to the most precious childhood in life, and there are many things better than money worth pursuing, otherwise it will be a little regrettable to recall this time when he grows up. No amount of money can make up for it. The child is very clever. If he is well guided, he will listen.
