Looking back,we see wise men exist in every dynasty and era in mankind's history.It is the wisdom of these men that moulded and changed the trajectory of the history.Their wisdom become the topics of our daily conversations,the focus of our history books and even anecdotes that are widespread across the globe.
It Chairman Mao had no wisdom,we wouldn't have had the new China and the happy life we are living now.If Edison had no wisdom,we would probably be still living in the dark during nights.If Albert Einstein had no wisdom,we wouldn't have got our knowledge about the universe,about space and time.
As ordinary people,we don't need to become wise men like the ones I have just mentioned above.Yet we still need to learn and try to gain wisdom in everyday life.Wisdom is necessary for our studies,work and even entertainment.With wisdom,we may not become a great person,but at least we can be decent.
