What is Tetraphobia ?

Tetraphobia is a fear or anxiety about the number 4. Tetraphobia is a superstitious belief commonly believed in East Asia such as China, Japan, Korea, and Taiwan. And the number 4 as much as possible avoided its appearance because it will bring bad impact. They reasoned sounds from number 4 if pronounced resembling the sound of the word death in their language.

Wedding, Restaurants and Hotel.

In addition, 14, 24, and others are also avoided because they contain 4 in those numbers. In these countries, the 4th-story building floor is usually replaced with 3A. Likewise table numbers in restaurants, weddings or other social gatherings, a table containing number 4 is revoked and replaced with another number.

And it turns out this tetraphobia superstition has also been worldwide, as a result of the many businessmen from East Asia, especially China that spread to all areas of business in the world.
