The Unlucky Number 4: The number four (四, sì) is extremely unlucky because it sounds nearly identical to the word for “death” (死, sǐ). Consequently, many buildings in China, from hotels to residential apartments, will completely skip any floor with a '4'. You will often see an elevator panel go from floor 3 to 5, or 13 to 15. The 4th, 14th, and 24th floors are often omitted.
The Lucky Number 8: The number eight (八, bā) is the luckiest number as it sounds similar to 发 (fā), which means “to prosper” or “wealth.” Apartments on the 8th floor are highly sought after and can even be more expensive.
Other Good Numbers: Six (六, liù) is considered good because it sounds like the word for “smooth” (溜, liù), implying a smooth and easy life. Nine (九, jiǔ) is also auspicious, historically associated with the Emperor and longevity.
