Every ethnicity has its taboos, what is for Chinese?👀
Number 4 is avoided by Chinese, because 4 is pronounced similar with "dead" in Chinese. In some new buildings, they even skip 4, 14, 24... floor, they call 4 floor 3a or 3b instead of 4 on the elevator buttons, just likes the Westerner resist the number 13. Also, Chinese refuse number 4, 14, 44, 444,4444 for their door number.
In contrast, Chinese like 3, 13, 23, 33...because 3 the pronunciation is similar with "live" especially in Cantonese, that's totally upside down with the Western.
What's yours?
