你还是我一碰就痛的软肋
[nĭ hái shì wŏ yī pèng jiù tòng de ruăn lèi]
"You Are My Soft Rib that Hurts on Touch" means that someone is an essential yet vulnerable part of the person’s life; often referring to a lover or family who causes emotional pain when treated improperly. It symbolizes both closeness and weakness.
