It is said that there is a custom in Guangzhou that after a new house is built, parents can't live on a higher floor than their children, otherwise it will be bad for their children's future life, right? This is a traditional cultural custom, and the back can be done according to the requirements of parents. After all, our parents are old, and we can't ask them to live higher than us. This will bring fatigue to parents, and it doesn't matter how high young people climb. Parents' health is not like that of us young people. We should understand that different places have different customs. It's hard to say, but you can't know until you have experienced it yourself.
