In name puzzles, I invented a method of choosing peoples' names by a 井 form. It is able to solve people's naming problems; it can be used in Chinese language teaching. This paper focuses on how to choose names without resorting to name culture. Therefore, I employ the name culture of predecessors, and then offer a Chinese dictionary as a tool, supplemented by a reference table of the surnames, and then recognize the shape, pronunciation and meaning of Chinese characters, which is called the 井 method. Through the actual operation with a dictionary, I changed someone of the Wang Family name to Wang Yan Sen (王琰升), and Bill Gates Di Zhao Heng (狄炤亨). The process of naming with a 井 is the cultural presentation of Chinese teachings.
