1. Studying abroad refers to a person going abroad or receiving various kinds of education, which can be short-term or long-term (from several weeks to several years). These people are called international students. Generally speaking, the way to study abroad is not only for students to apply to the schools that admit international students themselves, but also for many students to register their schools or choose their countries of study through study agents or study agents, or to use both together to assist in the study abroad procedures.

2. The word studying abroad has been omitted by international students. In the Tang Dynasty, in order to absorb the advanced culture of China, the Japanese government sent envoys to China many times. As a diplomatic envoy, the envoys in Tang Dynasty could not stay in China for too long, so the Japanese government sent overseas students and returned overseas students at the same time when it sent envoys to Tang Dynasty for the second time.

3. The so-called international students are those who stayed in China to study after Special Envoy Tang returned to China. When sending Tang envoys back to China, the foreign students will return home together. Later, the word "international students" was always used, and all students who stayed abroad to study were called international students.

4. The study agent is a study institution that provides services for students studying abroad to apply for study visas, and provides relevant consulting services for the selection and application of study institutions and the preparation of study materials. Applicants for studying abroad can entrust the related affairs of studying abroad to the study agent, and they only need to prepare and provide the application materials and test results for studying abroad.
