English has one famous number superstition — 13 — and it changes almost nothing about daily life; you might notice a hotel skipping the 13th floor and then forget about it. In China, number luck is a working system, not a curiosity. It touches which apartment people buy, what they pay for a phone number, the date they marry on, and the gift they don't dare bring. The whole thing runs on a single mechanism a beginner already has the tools to understand: homophones. Because a Chinese syllable is shared by dozens of different words, the sound of a number can summon another word entirely — and if that word is 发 "prosper" or 死 "death," the number inherits its glow or its shadow. Learn to hear those echoes and a lot of otherwise baffling behavior clicks into place.
The engine: numbers that sound like other words
A digit is lucky or unlucky in Chinese not because of what it means but because of what it sounds like. Each hanzi is one syllable, and huge numbers of words collide on the same syllable, so a spoken number drags a homophone along with it. Three of these links do most of the work:
- 八 (bā) "eight" → 发 (fā), as in 发财 (fācái) "get rich." Eight is the money number. The sounds aren't identical in Mandarin (a b isn't an f), and the association is actually strongest in Cantonese, where 八 and 发 rhyme even more closely — but the belief long ago went nationwide.
- 六 (liù) "six" → smoothness. Six carries the sense of things going without a hitch, mostly through the set phrase 六六大顺 (liùliù dà shùn) "double six, all smooth" and its echo of 溜 (liū) "sliding along easily."
- 九 (jiǔ) "nine" → 久 (jiǔ) "long-lasting." These are exact homophones, same syllable, same third tone. Nine means endurance — long life, a lasting marriage.
我特意挑了个尾号是八的手机号。
wǒ tèyì tiāo le ge wěihào shì bā de shǒujī hào
I deliberately picked a phone number ending in 8.
六六大顺，祝你新的一年顺顺利利。
liùliù dà shùn, zhù nǐ xīn de yì nián shùnshùnlìlì
'Double six, all smooth' — wishing you a smooth new year.
四: the number you'd rather not say
The shadow side is 四 (sì) "four" → 死 (sǐ) "death." The tones differ — 四 is fourth tone, 死 is third — so they're near-homophones rather than exact ones, but the resemblance is close enough that four is genuinely avoided. This isn't a quaint belief; it reshapes physical space. Many apartment and office buildings have no 4th floor on the elevator panel — the numbers run 3, 5, or 3, 3A, 5 — and skip 14 and 24 as well. Hospitals are especially careful, since death is exactly the association you don't want near the sick. Four gets shunned in phone numbers, license plates, and room numbers too.
这栋楼没有四楼，也没有十四楼。
zhè dòng lóu méiyǒu sì lóu, yě méiyǒu shísì lóu
This building has no 4th floor and no 14th floor.
医院的房间号大多避开“四”这个数字。
yīyuàn de fángjiān hào dàduō bìkāi “sì” zhège shùzì
Hospital room numbers mostly steer clear of the number 4.
八, 六, 九: the numbers people pay real money for
Because eight is lucky, it isn't just admired — it's bought. Shops price things at ¥88, ¥188, ¥888 far more often than chance would predict. Auspicious mobile numbers and license plates thick with 8s command real premiums: a plate with three or four 8s can sell at government auction for staggering sums, and a SIM card ending in 8888 costs extra at the phone counter while one full of 4s is discounted. The most famous single gesture: the Beijing Olympics opened at 8pm on 8/8/2008. Nine, meaning "lasting," is favored for weddings and love; six smooths business openings and moves.
带三个八的车牌，拍卖价能到几十万。
dài sān ge bā de chēpái, pāimài jià néng dào jǐshí wàn
A license plate with three 8s can go for hundreds of thousands at auction.
很多情侣选九月九号结婚，图个长长久久。
hěnduō qínglǚ xuǎn jiǔ yuè jiǔ hào jiéhūn, tú ge chángcháng-jiǔjiǔ
Lots of couples marry on September 9th, hoping for 'everlasting'.
The pricing and floor conventions behind all this get their own treatment on prices and shopping and floors and grades; the way phone and room numbers are read digit by digit is on phone and room numbers.
The internet's number code: 520, 1314 — and 250
Young people have pushed the homophone game further, texting numbers as words. The famous ones:
| Number | Sounds like | Means |
|---|---|---|
| 520 (五二零) | 我爱你 (wǒ ài nǐ) | "I love you" — May 20 is an informal lovers' day |
| 1314 (一三一四) | 一生一世 (yìshēng yíshì) | "a whole lifetime, forever" |
| 88 (八八) | 拜拜 (bàibai) | "bye-bye" — sign-off (net-speak) |
| 666 (六六六) | 溜溜溜 (liūliūliū) | "awesome / smoothly skilled" (net-speak) |
| 250 (二百五) | — | "idiot, half-wit" — an insult |
The odd one out is 250 (二百五, èrbǎiwǔ), which for murky historical reasons means "idiot" or "half-wit." It is a mild insult, and its stigma is strong enough that people avoid saying 二百五 even for the plain quantity 250 — in speech they'll often say 两百五 (liǎngbǎiwǔ) for a price of 250 to sidestep the connotation.
五二零那天，他给女朋友发了个五百二十块的红包。
wǔ èr líng nà tiān, tā gěi nǚpéngyou fā le ge wǔbǎi èrshí kuài de hóngbāo
On 5/20 he sent his girlfriend a 520-yuan red packet.
你别骂人二百五，太难听了。
nǐ bié màrén èrbǎiwǔ, tài nántīng le
Don't call people a '250' — it's really rude.
For more of this digit-as-word texting culture, see net-speak and texting; the underlying reason so many words collide on one sound is on homophones and context.
Gifts: the present that says the wrong thing
The same sound-magic turns some perfectly nice objects into social landmines. The rule that trips up foreigners: a thoughtful, expensive gift can be taboo purely because of a homophone. Two are essential to know:
- Never give a clock. 送钟 (sòng zhōng) "to give a clock" is homophonous with 送终 (sòngzhōng) "to see off the dying / attend a funeral." Handing a clock to an elder reads as wishing their death. A wristwatch (手表, shǒubiǎo) is completely fine — the taboo is on the word 钟, not on timepieces.
- Don't split a pear with a loved one. 分梨 (fēn lí) "to divide a pear" sounds exactly like 分离 (fēnlí) "to separate, to part." Couples and close friends avoid sharing one pear; giving pears to newlyweds or the sick is off.
你可别送钟给长辈，“送钟”跟“送终”同音。
nǐ kě bié sòng zhōng gěi zhǎngbèi, “sòng zhōng” gēn “sòngzhōng” tóngyīn
Whatever you do, don't give a clock to an elder — 'give a clock' is a homophone of 'see off the dead'.
恋人之间不要分梨吃，怕的就是那个“分离”。
liànrén zhī jiān bú yào fēn lí chī, pà de jiùshì nàge “fēnlí”
Couples shouldn't split a pear — the thing they fear is that 'separation'.
A few more move by the same logic: an umbrella (伞, sǎn) echoes 散 (sàn) "to break up," and shoes (鞋, xié) suggest walking away. Gifts are ideally given in even numbers — 好事成双 (hǎoshì chéng shuāng) "good things come in pairs" — but four is excluded, and cash in a red envelope avoids amounts built on 4.
Common Mistakes
1. Bringing a beautiful clock as a gift to grandparents. The nicer the clock, the worse the message — swap it for a watch.
❌ 我给爷爷买了个漂亮的钟当生日礼物。
wǒ gěi yéye mǎi le ge piàoliang de zhōng dàng shēngrì lǐwù
Unlucky — gifting a 钟 (clock) to an elder evokes 送终 'attending a death'.
✅ 我给爷爷买了块手表当生日礼物。
wǒ gěi yéye mǎi le kuài shǒubiǎo dàng shēngrì lǐwù
I bought Grandpa a watch for his birthday — a 手表 carries no taboo.
2. Putting 400 in a celebratory red envelope. Any amount resting on 4 is avoided for weddings and birthdays; reach for 6 or 8.
❌ 婚礼上我包了四百块。
hūnlǐ shàng wǒ bāo le sìbǎi kuài
Unlucky — 4 (四) echoes 死 'death', wrong for a wedding gift.
✅ 婚礼上我包了六百块。
hūnlǐ shàng wǒ bāo le liùbǎi kuài
I put 600 in the wedding envelope — 6 is smooth and auspicious.
3. Sharing a single pear with your partner to "save one." Cut two, or cut something else.
❌ 就一个梨，我们俩分着吃吧。
jiù yí ge lí, wǒmen liǎ fēn zhe chī ba
To a partner this is loaded — 分梨 sounds like 分离 'to part'.
✅ 我再拿一个，咱俩一人一个。
wǒ zài ná yí ge, zán liǎ yì rén yí ge
I'll grab another so we have one each — no dividing, no bad omen.
4. Saying 二百五 for a price and getting a laugh. Use 两百五 aloud to keep the "idiot" reading at bay.
❌ 老板，这个二百五卖不卖？
lǎobǎn, zhège èrbǎiwǔ mài bu mài?
Risks a chuckle — 二百五 doubles as the slang for 'idiot'.
✅ 老板，这个两百五卖不卖？
lǎobǎn, zhège liǎngbǎiwǔ mài bu mài?
Boss, will you sell this for 250? — 两百五 avoids the slur.
Key Takeaways
- Number luck runs on homophones: a digit's sound summons another word — 八 (bā) → 发 (fā) "prosper," 九 (jiǔ) → 久 (jiǔ) "lasting," 四 (sì) → 死 (sǐ) "death."
- Eight is lucky and literally valuable — prices, plates and phone numbers full of 8s cost more; four is avoided, so buildings skip the 4th floor and hospitals dodge the digit.
- The internet code turns numbers into words: 520 = "I love you," 1314 = "forever," while 250 is a live insult.
- Gift taboos are homophone traps, not object taboos: no clock (送钟 ≈ 送终) and no shared pear (分梨 ≈ 分离); a watch and an unshared pear are fine.
- Give gifts and cash in even, non-four amounts — 好事成双, "good things come in pairs."
