The number 4 in East Asia: superstition explained

What people believe, where it comes from and what is really going on.

The belief

In Chinese, Japanese and Korean, the number four is avoided because its pronunciation is close to the word for death. Hospitals may have no fourth floor or room 4, and gifts in sets of four are avoided.

Where it comes from

The belief is an example of a pun carrying a superstition. In Chinese, "si" (four) and "si" (death) differ only in tone. In Japanese the number can be read "shi", the same as death, and "yon" is used instead in daily life.

What is really going on

It is a matter of courtesy: if you give gifts in East Asia, avoid sets of four, as with the clock.
