History appears as teaching history. My major is ancient history of China, modern history of China and ancient history of the world, modern history of the world, as well as historical philology, historical geography, folk history, political system history, historiography history, western historiography history, national history and so on. I finished my major in the first three years, then I took a course in the last year, and then I worked as an intern. After that, I hope to help you.
