I want to raise up an idea at this point, sometimes, when consider both side of a question, we’d better compare the pros and cons of it. Moreover, some historic change would come with violence, and those are unavoidable at some points, also simultaneously those benefits outweigh huge negative impacts. Such person as Christopher Columbus, such person as the first emperor of China in Qin Dynasty. Yin Zheng was described as a tyrant in history books, taking the lives of people and holding blood in his hands. But, if take a look in the opposite perspective, he unified currency, language, etiquette and music by his own.

For example, he opened the gate of international business, and being an inspirational public figure.
