Senior sales are called channel managers, and some are called BD; Follow the project, the project poor sit in the office and dealer every month, and occasionally go to the branch to take oil and water to the grassroots; Get rid of the boss for a few minutes, earn ten years at a time, and have no worries about food and clothing.
