千家万户
qiān jiā wàn hù · HSK 7
every family (idiom)
🏘️ 千 thousand + 家 homes + 万 ten-thousand + 户 households = every family
A four-part count: 千 (thousand) and 万 (ten-thousand) are big round numbers, while 家 (home) and 户 (household, literally a door) name the units. Stacking huge numbers onto homes is the idiom's way of saying all households everywhere.
千 — person 人 with horizontal stroke
Originally derived from the character 人 (person) with an added horizontal stroke, used as a numerical marker meaning 'thousand.' Some scholars link the stroke to a tally mark indicating a large count. Over time it became the standard numeral for 1000.
家 — roof 宀 + pig 豕
Originally a pictograph of a pig under a roof, since domesticated pigs were kept in or under the home in ancient China. Over time the meaning broadened from 'household' to 'family,' and by extension 'home' or a specialist (as in 专家, 'expert').
万 — top 一 + 𠃌 (hook) over 丿
Originally a pictograph of a scorpion, used in oracle bone script. It was borrowed phonetically to mean 'ten thousand' and the original scorpion sense was lost. The traditional form 萬 shows the scorpion more clearly; 万 is a simplified variant long used as a common shorthand.
户 — single-leaf door (half of 門)
户 is a pictograph showing a single-leaf door, originally drawn as half of 門 (a double door). It came to mean 'door,' then by extension 'household' or 'family,' since a door marks one dwelling. Today it commonly means 'household' or 'account.'
