Take what I know as an example. For example, many students are studying in New Oriental and want to be teaching assistants. One class is about 50 yuan, and they can earn 100+ in six days. They are not tired, and English and other subjects can also be improved (the grade is low, but there is room for further study). Not only make up lessons, but also interest classes, which are particularly well paid. Now the education industry is very profitable.
Or the most common sales. It means to exercise your face and communicate with others during the holidays (the 6th or during the winter and summer vacations). At present, most graduates (I am also a second major, and my major is not particularly good) usually graduate from sales and account manager. Doing sales in advance helps me a lot, and the cost performance is super high-I lost ten pounds (smiling face) and my salary is good.
The above is a relatively cost-effective salary. For a good resume, you can also get a certificate without considering salary, because internships in top enterprises in the industry are usually unpaid, but having a certificate is very helpful for future work!
