Time is always moving forward, so everything in the world needs to change over time. Even if politics is the same, there will always be a new generation of people to replace the previous generation. This is a natural development process. In fact, it is not that young people can accept more. If you are a person who is willing to accept new things, then even if you are 50 or even 70 years old, you can still accept new things. If you are not such a person, then you are young and useless.
