The company's business covers the whole country, and there are no other branches in the country, that is, like a company in Beijing, he sells users across the country, but never set up an office or a branch, relying on the Beijing company's salesman to promote, then there will be a possibility of travel. So this is basically not divided into industries (in addition to telemarketing-based businesses), as long as the industry has a company that he is facing customers across the country and no branches, then the company's salesmen have a high probability of business travel.
