I have an question. the question is what are the importance of enlish in management, marketing, profession, job position, banking, society?
That depends on where you are. In Germany, for example, being able to speak English is a very important skill and it's hard these days to get a good job without at least some English. But in China, this may not be the case.
It also depends on your job. If you are in banking, the chances are you will need good English to be able to do any kind of international trade. But if you work for a company that buys rice from Korean farmers and sells it in Korean supermarkets to Koreans, English might be not be quite so important.
Globally, English is the most important language for international trade and commerce.
