Parents' education needs a bowl of water, so please respect your child's choice.
When two children have an argument, one of them always gives in. This sentence seems to be the unspoken rule of peace by default, but it doesn't mean that older children should take the initiative to take responsibility. Parents should deal with problems fairly, educate their children to admit their mistakes, learn to share with others and learn to be modest.
Brothers and sisters are the closest relationship in the world, and it should be "love" rather than "letting" or "listening" to maintain this relationship.
With love, the big one will naturally give way to the small one, and the small one will listen to the big one.
