Human being is not only taking the most important role in the history but also in the modern time. They always cannot stop asking what the human being is; how could be acting as human being, and etc such questions around us for many decades.
As human being, we all know that we have to follow some certain laws, rules, morals and customs not because of enforcement, in fact, it is our innateness. Being a moral person is easy to say but hard to do. For instance, keep away from the drugs, odd behaviors, over drinking, such behaviors cause troubles not only for you but also others. In common, people have their own standers since different people have different judgments. However, from the point view of generals, being a good person who has to follow the morals which are human beings make for us.
It is really hard to tell what the stander is to become a good human being, there is no such solution or method to trace, the only way is follow your heart and choose the right way to do.

what is the defination of a good man,you may ask. i don't really know.because nobody if perfect.nobody is 100% good.what we can do is try our best to do what we are suppposed to do.maybe a good man just means who tries it hard.

as i think, a good man should try to do the following things. hhe should never do things which are harmful to others on purpose. instead, he should try his best to help others. that is the most important thing. and,to be better, he'd better know how to show his ethusiam and sympethm.

a good man always respect people and is always respected by others. that's it.
