You need to bring a girl to apply, because there is a shortage of men and women in this industry, and the salary is around 2000-3000. Some big companies provide free accommodation and living expenses, but they have high requirements for technical and theoretical knowledge, long study time (depending on their performance), and they have to take a qualification examination before they can take up their posts (three years ago). In some small shops, you have to pay tuition (500- 1000), but they can teach you for almost a month. I suggest going to a big company, which has a bright future and can learn something, but it will be strict and semi-militarized. In this line of work, is it harmful to your health or a youthful meal? Unless you have the ability to develop into management, you should learn something else. After doing it for several years, my body collapsed.
