First of all, parents feel that children are their own continuation and have the obligation to fulfill their unfinished wishes. China has had such a saying since ancient times, such as the foolish old man moves mountains. When Gong Yu moved mountains by himself, someone asked him what to do if he died. Gong Yu replied that he would have his own offspring after his death. From this story, we can easily see that China's concept of parental education has always been like this, so there is a reason why parents always expect their children to fulfill their unfinished wishes.
Secondly, parents feel that their mission can only be completed if their offspring are better. For most parents, they hope their children can become better, change the current class and live in a higher class. China's parents have a natural sense of responsibility for their children, and no matter how old they are, they want them to be under their control. Therefore, many children have to listen to their parents when looking for a job, and they have to listen to their parents when looking for a partner. If parents feel that they have not become singers, they will train their children to the performing arts career regardless of their children's wishes. There are many such things.
Personally, I think that parents' love for their children is right, but they should use the right way and don't impose their ideas on their children, so the children will be very unhappy.
