Whether it is necessary to study abroad depends on several aspects:

1. In my present situation, if I get good grades and can find a good job after graduation, there is no need to study abroad.

2. Look at the family's economic situation. If there is no financial pressure at home to support studying abroad, then going out still has many benefits.

3. Look at the students' desire to learn. Many children go out with a playful attitude and regard learning as a burden. There is no need to study abroad.

4. See if the students' attitude towards studying abroad is positive.

In fact, studying abroad is mainly for students to create contact difficulties and exercise opportunities in unfamiliar environments. To tell the truth, today's students, in domestic universities, are too comfortable to study and live. They were born in sorrow and died in happiness. The lessons of the ancients are wise words.

Before studying abroad, it is generally necessary to do a lot of adequate preparation for studying abroad in order to be foolproof. As a reminder before studying abroad, students are advised to fully understand all available resources around them before going abroad, so as to solve problems in study, life, psychology, health, laws and regulations, safety and so on in time.

Before going abroad, you can learn a core technology of teaching Chinese as a foreign language, and get the three-certificate joint examination certification of Hanban Ministry of Human Resources and Social Security International Certification Association. After going abroad, you can also communicate with foreigners in various ways.
