I remember a few years ago, the boss just like we used to say, we are selling "Micro Cooling Fan", to be honest with the customer communication, do not brag, just to the customer can actually solve the problem, to get the trust of customers, if customers view us as friends, that business would have a major success. He said too right, once I know he visited a "Micro Cooling Fan" client when he was to me a business card, so keep in touch, and later became friends, he did not think the fan is also useful, asked me after the sample tests, get an order to me, two years ago, has been a good relationship. Only this customer trust me too, and I "Micro Cooling Fan" is poorly understood, in order not to trouble, eventually I told him I could not help him.
