Basic Info
- Chinese Idiom: 比翼双飞 (Bǐ yì shuāng fēi)
- Pinyin: bǐ yì shuāng fēi
- Literal meaning: “Flying wing to wing as a pair.”
(比翼 = wings close together / wing to wing; 双 = a pair / both; 飞 = to fly)
Also written as “比翼齐飞” (bǐ yì qí fēi).
The legend behind it: The 比翼鸟 (bǐ yì niǎo) is a mythical bird said to have only one eye and one wing on each side – a male and a female must fly together, wing pressed to wing, or neither can fly at all.
Figurative Definition
It is a poetic image of devoted married love – a couple who are inseparable companions, moving through life side by side, in perfect harmony. Like the legendary one-winged birds that can only fly as a pair, the husband and wife complete each other and cannot thrive apart.
It is used to praise:
- A loving, harmonious marriage – “祝你们比翼双飞，白头偕老。”
- A couple advancing together – in career, life, or shared goals.
- Inseparable companionship – two people always moving in the same direction.
In short: flying wing to wing – a couple inseparable in love and life.
A useful distinction from its near-twin “比翼连枝” (bǐ yì lián zhī):
- 比翼双飞 emphasizes movement and shared journey – flying together through life.
- 比翼连枝 emphasizes intertwined existence – joined branches, fused lives.
Cultural & Historical Origin
The image of the 比翼鸟 is ancient in Chinese literature. This idiom is cited from the Jin Dynasty poet Lu Ji (陆机), in his poem Imitating “Northwest There Is a High Tower” (《拟西北有高楼》):
“不怨伫立久，但愿歌者欢；思驾归鸿羽，比翼双飞翰。”
(“I do not resent standing here so long; I only wish the singer joy. I long to ride the feathers of the returning geese, and fly wing to wing as a pair.”)
The poet longs to fly side by side with the one he loves, like paired birds crossing the sky together. The image was later made immortal by Bai Juyi’s (白居易) Song of Everlasting Sorrow (《长恨歌》):
(“In heaven, may we be wing-to-wing birds; on earth, may we be branch-joined trees.”)
From these poetic sources, “比翼双飞”, became one of the classic Chinese expressions for devoted, harmonious married love.
Key Lesson
The best love is a shared flight – two equal beings moving in the same direction. The image is beautiful: the birds cannot fly alone, yet neither is carried by the other – they fly together, wing to wing. It teaches that a strong marriage is a partnership of equals: two people who support each other, move in harmony, and complete each other’s journey. It is not about one person carrying the other, but about flying as one.
Cultural Note
In Chinese culture, “比翼双飞” is one of the most beloved expressions of married love and partnership. It appears in:
- Wedding blessings and decorations – wishing the couple a lifetime of harmonious companionship.
- Love poetry and literature – the standard image of devoted couples.
- Modern usage – often used for couples who advance together in career or life: “夫妻俩比翼双飞，事业都很成功。” (“The couple flew wing to wing – both succeeded in their careers.”)
- Art and symbolism – paired birds appear in Chinese painting, embroidery, and wedding motifs.
Its near-synonyms are “夫唱妇随” (fū chàng fù suí – “the husband sings and the wife follows,” meaning marital harmony), “凤凰于飞” (fèng huáng yú fēi – “the phoenixes fly together”), and “鸾凤和鸣” (luán fèng hé míng – “the phoenix and the luan sing in harmony”). Its opposites are “劳燕分飞” (láo yàn fēn fēi – “the shrike and swallow fly apart,” meaning separation or divorce) and “鸾凤分飞” (luán fèng fēn fēi – “the phoenixes fly apart”).
