Chinese people have always considered the number four to be unlucky because its pronunciation in Mandarin is similar to that of "death." But there is a company in Taiwan which doesn't give a darn, and has not only chosen the Chinese name "404 Technologies," they even have their offices on the dreaded fourth floor of the building where they are located.
華人向來最忌諱與「死」字諧音的數字「4」，不過台灣有家公司卻不信邪，不但取名「四零四科技」，連地址所在的樓層都是 4 樓。
