What is the business manager recruited by China Telecom?

But there are levels,

Usually just go out to run customers and pull business.

Better customers are assigned to you, you just need to pull these customers well, and basically you don't have to go outside to pull business.

Top vip only needs to manage a few big customers assigned to you, follow up all the time before and after sale, and stand by 24 hours. People will come to you for anything, and the rest is your business. But this kind of non-recruitment requires internal promotion/job transfer.

I guess you should be talking about the first two.
