A few days later on a Saturday, they came to my shop again. From his friend, I learned that they have been in my shop in early time. As didn't found me, the Korean customer  went to buy something else. After that he still come back to my shop, although there are many competitors next to my shop. He chose to wait for me and adhered to buy the test probe in my shop. He said to his friend I’m a good salesman and he want to buy my products. I was very grateful to the customer for trusting and praising me. This time we talked a lot.

A month later, the Korean customer came to my shop alone. We said hello like old friends. He speak limited Chinese, I speak poor English. With this unique way, we communicated with each other. Yes, we've built up a friendship. It all started from our gratitude and patience from each other.
