Numerical phases have rich cultural connotations and connect closely with culture. Along with the extension of China's reform and opening up policy, cross-cultural communication tends to be wider. The comparative research on cross-cultural languages is very important. Because of different cultural backgrounds, the cultural connotations of Chinese and English numerical phases are quite different. This paper tries to make a comparative research on the cultural connotations of numerical phases (include numbers from one to ten), in order to reveal the importance of cultural connotation characteristics in cross-cultural communication.
