Replying to [delaynomorehai]:
This is a method which usually used by companies in Shenzhen as I know. But there is a disadvantage, that is there may be a sales person who is not able to exploit the market he/she is in charge of, and another sales person who with strong exploitation ability just can go into it...
So I think we can use this method only if we have had many clients in every region we divided into.
