Be a little interpreter

Today I am very happy, because I have helped a german. After finishing my homework, I decided to have a walk. In the street, there was an old man painting and selling chinese traditional paintings. I was really interested in these kind of paintings. After a while, a german came. He wanted to buy a painting. He only spoke a little chinese. The painter had difficulty understanding him. I decided to help him. I asked him what he wanted, and so on. Then he told me that he wanted to buy two pictures, one for his sister and the other for himself. He liked chinese traditional paintings very much, it was really lifelike. I was moved to hear that the foreigner liked chinese culture, and I decided to learn more about chinese traditional paintings.
