The number 4 holds a special place in Chinese culture.

In China, the number 4 is considered to be an unlucky number, and many people try to avoid using it whenever possible.

This superstition is known as “tetraphobia” and is rooted in ancient Chinese beliefs and practices.

Number 4 (四 sì) sounds like 死 (sǐ; to die). Because of its negative association with death, many buildings in China do not even have a 4th floor. The number 4 rarely appears on house and door numbers, or car license plates.
