01An ominous homophony: 4 sounds like "death"
In East Asian languages marked by Chinese influence, the digit 4 is phonetically close to the word "death". In Japanese, 四 (shi) and 死 (shi, "death") are strict homophones; in Korean, 사 (sa) stands for both "four" and "death" (死). In Mandarin, 四 (si, 4th tone) and 死 (si, 3rd tone) differ only by tone, a near-homophony sufficient to sustain a persistent superstition. Offering a gift made up of 4 units can therefore be read as a morbid wish.
02Tetraphobia: a documented superstition
This aversion to 4, tetraphobia, is widely attested in China, Taiwan, Japan, Korea and Vietnam. It shows up beyond gifts: hospital floors or rooms without a number 4, product lines that skip 4, plates and numbers avoided. It is strongest in Japan and Korea, where the homophony is exact, and somewhat more relaxed in mainland China, where the difference in tone softens the effect.
03The trap of gifts grouped in fours
In a business context, offering a set of 4 items (4 pens, 4 cups, 4 samples) to an East Asian partner can come across as clumsy, or even malicious. The risk is less a systematic major offense than discomfort and a signal of cultural ignorance. Conversely, lucky even quantities are valued, particularly 8 (八 ba), associated with prosperity (发 fa).
04Regional variants and limits
Strictness varies: strict in Taiwan, Hong Kong, Singapore and the traditional Chinese-speaking world; real but uneven in Japan and Korea; more diffuse in Vietnam. The taboo mainly concerns the number 4 and its perceived derivatives (14, 24, 40-49); it is not a universal rule, and many young urbanites pay it little attention. Over-interpreting every even quantity would be the opposite mistake.
05Practical precautions
For a gift intended for East Asia, check that the number of items is not 4 and prefer 2, 6 or 8. If the mistake has already been made, a simple apology and a replacement gift in a favorable number are enough to dispel the awkwardness: the impact of the incident is social and symbolic, rarely contractual. Asking a local colleague for advice settles the doubt.
Historical origins
Offer gifts in lucky, even quantities (2, 6, 8, 10). Before wrapping, check that number
Practical recommendations
To do
- Offrir en quantités paires favorables (2, 6, 8 ; le 8 évoque la prospérité). Vérifier le nombre d'éléments avant emballage. En cas de doute, demander à un interlocuteur local. Reconnaitre simplement une erreur et la remplacer par un nombre favorable.
Avoid
- Eviter les ensembles de 4 (et 14, 24, 40-49) destinés a la Chine, au Japon, a la Corée. Ne pas dramatiser : le tabou crée un malaise, pas systématiquement une rupture. Ne pas surinterpreter toute quantité paire. Ne pas se vexer d'un refus poli.
Neutral alternatives
Sets of 2, 6, 8 items (even and lucky). Individual gifts not bundled. Greeting cards + a single premium gift.
