<human>:  What is the significance of the number four in Chinese culture?
<bot>: The number four is considered to be unlucky in Chinese culture because the Chinese pronunciation of “four” is quite similar to the pronunciation of “death”. As a result, many Chinese people avoid using the number four wherever possible and often substitute it with another number. Even today, certain buildings in China will not have a fourth floor or any room with a number containing fours in it.
