Yes, whether a person can be reasonable depends on the depth of the problem and his understanding of the person, not his age. If a person says that he doesn't know how to reflect on himself or make progress, he will be as naive as a child even if he lives to 80 years old.

In life, we will find that many people look at problems from various angles. Some people can only see the surface, while others can see the essential connotation through the surface, thus gaining a deeper experience. This is related to personal cultivation and people's environment. People like the older generation may have such an idea because of their limited educational knowledge and social environment. For modern young people, especially those born after 1990 s and 1900 s, everyone lives in a very trendy era. Now it is an information society, so they are exposed to a variety of information, so they are exposed to more information than the older generation.

I believe that the young people in the future will be more brilliant. Shine on you is better than blue, and it has been brilliant for hundreds of years!
