In fact, A Dai looks a little different from him, because there is always a distinctive snot lying down, but in fact, A Dai is really a smart boy, just like Xiao Xin worships A Dai. Being able to educate children so well will naturally attract more people's attention to their parents, because family education is also the most influential part for children. However, from the beginning of Crayon Shinchan to now, A Dai's parents have never appeared, while Zhengnan, Nini and feudal mother, both friends, have appeared frequently.
In fact, it is obvious that this should be a mystery deliberately set by the author, but in an animation, it is revealed that the picture of staying at home for dinner, although common, is quite different from Xiao Xin's home. Children watching TV know that A Dai's family conditions are very good, and A Dai's eating tools are actually knives and forks. In fact, it is really dangerous for a five-year-old child to use a knife and fork.
In fact, from this scene, it can be proved that A Dai's parents' income is very good, and for such a family, I believe that parents will not be particularly stupid and will not put their children in danger, so it can be proved that A Dai has been eating with knives and forks since childhood. So when she uses a knife and fork, her parents won't think it's unsafe.
