月老你牵错线了
[yuè lăo nĭ qiān cuò xiàn le]
"Mr. Moon (god of marriage) tied the wrong knot" comes from Chinese folklore about Mr. Yue Lao, who ties together destinies with a red thread of destiny. This phrase humorously implies fate went astray by mistakenly uniting couples or individuals in unintended ways, suggesting an unconventional match not typically perceived as suitable at face value.
