Learn 12 Chinese love idioms with pinyin, precise meanings, usage notes, and examples for attraction, devotion, and lasting relationships.

Chinese love idioms are compact, but they are not interchangeable. Some describe the instant attraction at the beginning of a romance; some describe mutual understanding; others are blessings for a couple who have already chosen a life together.
The examples below show where each idiom sounds natural. Several are common in wedding messages and written captions but would feel unusually formal in an ordinary conversation between partners.

What Chinese idiom means true love?
There is no exact single equivalent. 两情相悦 emphasizes mutual love, 心心相印 emphasizes deep understanding, and 相濡以沫 emphasizes loyal support through hardship.
Which Chinese love idioms are suitable for a wedding card?
白头偕老, 天长地久, and 比翼双飞 are traditional positive wishes for a married couple. 相濡以沫 is meaningful too, but focuses more on supporting each other through difficulty.
Are all four-character Chinese phrases idioms?
No. Many fixed expressions have four characters, but a 成语 usually has an established conventional meaning and often a literary or historical source. A newly assembled four-character slogan is not automatically a chengyu.
