Chinese folklore considers the number 4 to be unlucky because the pronunciation of “four” in Chinese sounds like the pronunciation of the word “death”.

The informant is an American who previously lived in Shanghai for two years and attended an international school.

G explained that while living in Shanghai she noticed that some buildings didn’t have a fourth floor. After realizing this omission, she began to notice that the number four was avoided culturally if possible. She asked some school friends about it and they explained that in Chinese folklore it’s unlucky to use the number 4 because it sounds like the word death. G found this superstition to be interesting and continued to notice it, but she never believed in it herself.
