Why can four feel unlucky while eight is highly desirable? The answer lies in the sound of Mandarin, and it appears everywhere from lift buttons to phone numbers.
If you have ever seen a lift in China with no fourth floor, or heard of someone paying extra for a phone number full of eights, you have already encountered Chinese number symbolism.
For Mandarin learners, these customs are a useful reminder that language does more than communicate literal meaning. The way a word sounds can also shape traditions, choices and even prices. Here is why the number 4 is considered unlucky in China, why 8 is seen as fortunate, and what visitors should know.
Why Is the Number 4 Unlucky in China?
Some buildings skip the fourth floor because of the number’s unlucky association.
The number four is written 四 and pronounced sì. It sounds similar to 死 (sǐ), the word for “death” or “to die”. The tones are different, but the resemblance is close enough to give four an unlucky association.
This is why some people prefer to avoid four in phone numbers, car number plates, hospital room numbers and addresses. A residential building or hotel may label the floor after three as five, much as some buildings in Western countries omit the number thirteen.
There is no single rule followed across China. The custom varies by region, generation and personal belief.
Why Is 8 a Lucky Number in China?
Phone numbers and car plates containing several eights can be especially desirable.
The number eight, 八 (bā), is associated with prosperity. Its sound is linked with 发 (fā), as in 发财 (fācái), meaning “to become wealthy” or “to prosper”.
Because of this positive connection, eight is one of the best-known Chinese lucky numbers. A phone number, address or car plate with several eights may be considered more valuable, and some buyers are willing to pay a premium for a particularly auspicious sequence.
Eight also appears in dates chosen for weddings, business openings and other important events. A sequence such as 88 or 888 can make a date, price or number feel especially fortunate.
The opening ceremony of the 2008 Beijing Olympic Games began at 8:08 p.m. on 8 August, 08/08/08, a memorable use of the number eight’s auspicious symbolism.
How Sound Creates Symbolic Meaning
The connection between four and death, or eight and prosperity, is based on 谐音 (xiéyīn): words that sound alike or nearly alike but have different characters and meanings.
Sound-based associations appear throughout Chinese culture. They can influence which foods are served at celebrations, which gifts are appropriate and which dates feel lucky. A number does not carry this meaning because of mathematics; it gains meaning through language.
These associations connect with the broader idea of 吉利 (jílì), meaning “auspicious” or “lucky”. Some families take auspicious choices seriously when planning a wedding, moving home or opening a business. Others simply enjoy them as a familiar cultural tradition.
Where You May Notice Lucky and Unlucky Numbers
Formal gifts may be arranged in auspicious quantities such as six or eight.
Number symbolism can appear in many parts of everyday life:
- Buildings: Some hotels, hospitals and apartment blocks omit floors or room numbers containing four.
- Phone numbers: Repeated eights may make a number more desirable, while repeated fours may be avoided.
- Car number plates: A plate with a lucky sequence can attract a higher price.
- Important dates: Couples and businesses may choose dates containing six, eight or nine.
- Gifts: For a formal celebration, people may avoid giving items in sets of four and choose six or eight instead.
Six, 六 (liù), often suggests that things will go smoothly. Nine, 九 (jiǔ), sounds like 久 (jiǔ), meaning “long-lasting”, so it can be a positive choice for relationships and longevity.

A Short Cultural Scenario
A: 这个电话号码里有很多八，很吉利！
Zhège diànhuà hàomǎ li yǒu hěn duō bā, hěn jílì!
This phone number has lots of eights. It’s very lucky!
B: 对啊，我特意选的，而且没有四。
Duì a, wǒ tèyì xuǎn de, érqiě méiyǒu sì.
Yes, I chose it on purpose, and it doesn’t have a four.
What Should a Visitor Do?
You do not need to avoid four in ordinary conversation, and nobody will expect a visitor to reorganise every choice around lucky numbers. Simply being aware of the custom is usually enough.
For an important gift, wedding or business opening, however, it is thoughtful to avoid presenting four identical items. Six or eight may feel more celebratory. If you are unsure, ask your host or a Chinese friend; customs differ between families and situations.
A Common Misunderstanding
Not everyone in China is afraid of the number four. Some people take the association seriously, some make practical choices because other people value it, and others barely think about it at all.
It is also perfectly normal to see four in dates, prices, addresses and everyday speech. Chinese number superstition is a flexible cultural pattern, not a universal ban.
Final Cultural Takeaway
The unlucky reputation of four and the popularity of eight reveal how closely sound and symbolism are connected in Mandarin. Once you recognise 四 (sì), 死 (sǐ), 八 (bā) and 发 (fā), everyday details such as lift buttons, phone numbers and gift sets start to tell a richer cultural story.
Understanding these connections is one more way to make your Mandarin feel connected to real life.
