The number 4 is considered unlucky because it sounds almost identical to the Chinese word for death, while the number 8 is lucky because its pronunciation sounds like the word for wealth or fortune. This cultural phenomenon is rooted entirely in homophones, which are words that sound the same but have completely different meanings.
The phonetic power of Chinese numbers
To understand why these numbers carry so much weight, you have to look at how they sound when spoken aloud in Mandarin and Cantonese.
- The Number 4: In Mandarin, the number four is pronounced sì. The word for death is pronounced sǐ. The only difference between them is the vocal tone. Because the pronunciation is so dangerously close, people connect the number directly to mortality and bad luck.
- The Number 8: In Mandarin, the number eight is pronounced bā. This sounds very similar to the word fā, which means to prosper, accumulate wealth, or strike it rich.
Because of these sounds, people treat the numbers as physical symbols of the concepts they mimic.
How this affects daily life and business
These beliefs are not just old superstitions. They actively shape modern economics, architecture, and daily choices across China, Hong Kong, and Taiwan.
If you travel or do business in these regions, you will see this play out in very specific ways.
- Building Elevators: Many high-rise apartments and hotels completely skip the 4th, 14th, 24th, and 34th floors. Just like the “unlucky 13” in Western culture, developers worry that people will refuse to live on a floor associated with death.
- Product Pricing and Phone Numbers: Phone numbers, license plates, and apartment numbers containing multiple 8s are highly prized and sold for premium prices at auctions. Conversely, addresses with the number 4 have lower market value.
- Corporate Events: The Beijing Summer Olympics opened on 8/8/08 at exactly 8 minutes and 8 seconds past 8:00 PM local time to ensure the ultimate amount of good fortune for the country.
The hidden language trap for foreigners
The ultimate mistake to avoid is assuming these number rules are exactly the same across every regional dialect in China.
While 4 is universally avoided, other numbers change their meaning depending on the regional language you speak. For example, the number 6 is considered highly lucky in Mandarin because it sounds like the word for “smooth” or “flowing,” implying your life will go smoothly. However, in Cantonese, the number 6 can sound like a slang word for a fall or drop.
When you pick numbers for business, marketing, or gifts, you must always verify how those specific digits sound in the local dialect of the exact city where you are operating.
