People are the creators of history. Although everyone's role in history is different in nature and degree, it will leave a mark on history. Without everyone's role, there can be no role for the masses. An individual refers to a single member of a social group and a member of society, and the role of an individual in history is different. Some people play a bigger role, others play a smaller role, some people promote the development of history, and some people hinder the development of history.
