月老给我把红线换成钢丝
[yuè lăo jĭ wŏ bă hóng xiàn huàn chéng gāng sī]
Yue Lao is a matchmaker god in Chinese folklore who connects couples with a red thread of fate. The user humorously suggests they want Yue Lao to replace this delicate red thread with steel wire, implying a desire for an unbreakable connection in love.
