The so-called "Bo" means learning from the past and learning from the present. Simply put, it is to understand the history of human development, such as what kind of thoughts people of all countries have had, what kind of major events have happened, and what kind of changes have taken place. And understand these related historical events and representative works (including declarations, etc. ). The so-called "elegance" is virtuous. It is very important to remind yourself of what is right and wrong at all times and correctly establish your own outlook on life and values. Only by establishing a correct outlook on life and values can we guide our actions and thoughts to develop in the right direction.
In short, Boya is the result of continuous accumulation. Of course, if you are still alive, it won't be too late. I don't know if you will achieve this goal, even if you can't, you will gain a lot by working hard towards this goal.
