Which has developed, the software engineer or the fitness instructor?

Software engineer, of course. The software industry is now supported by the state. Just look at all kinds of emerging software companies and you will know that the salary depends entirely on the ability, because the salary in the software industry is very attractive. Of course, high salary is for people with good ability. In large domestic IT companies like Baidu and Tencent, the annual salary of ordinary software engineers is around150,000, and that of smaller companies is around100,000, but the annual salary of people with average ability may be less, about 70,000. Most of the domestic software industry is still a lot of outsourcing enterprises, and the salaries of these enterprises are lower. If you have the ability, you can enter a foreign company with a salary of 200 thousand, such as Google, Microsoft and so on. It must be mentioned that the financial industry also needs software talents now, one is to research software for enterprises, and the other is to maintain its own background database. These salaries and benefits are very good.

I hope my answer can give you some inspiration.
