Three places where children look smart?

It is not unreasonable to judge whether a child is smart by looking at his eyes. Whether the child's memory is smart: If the child is not easy to forget something, then the child must have a good memory, be born smarter, and will be more relaxed in his studies and get better grades in the future. Do children have curiosity and love to laugh: children like to get to the bottom of things, or have rich imagination, which shows that their brains are well developed and will be smart in the future. It is said that "people who love to laugh are not bad luck", which has some truth.

We always attribute those clever children to innate genes. In fact, three points depend on nature and seven points depend on the day after tomorrow.
