Definition

连理枝

Literally means:

interlocked branches from different trees

Actually means:

a couple in love

连理, different trees whose branches are interlocked (which is rare sight, and it was considered as a lucky sign in ancient China).

The whole phrase metaphorically refers to a couple very much in love or intimate lovers. Commendatory.

连理,本来不同根的草木,其枝干连生在一起(这是自然界罕见的现象,古时被认为是吉祥的征兆)。

连理枝,比喻恩爱夫妻。也指关系亲密的人。具有褒义色彩。
