First, because the festival is very tossing.
Generally speaking, the festival that young people have to rush home will be the Spring Festival. One of the characteristics of the Spring Festival is that almost everyone wants to go home, so the situation is that it is hard to get a ticket. Even if tickets can be bought, the roads are crowded, and some people are far from home. For these people who are far away from home, it becomes more difficult to go home during the Spring Festival, so many people don't necessarily hate festivals, but
Family members use moral kidnapping to let you go home and reunite, and then make yourself very tired.
Second, festivals are meaningless.
When I was a child, I wanted to eat and drink, so the holidays were very interesting. It's different when you grow up. We can see that things are much richer now than in the past, so Chinese New Year is naturally not so rare. So even if you meet some big festivals, you won't feel anything special. I haven't seen anything to eat or drink. What's the fuss?
And it is always awkward to be with the older generation on holidays, because they have nothing in common, so they feel very uncomfortable.
