你生活在花花世界所以可以三妻四妾
[nĭ shēng huó zài huā huā shì jiè suŏ yĭ kĕ yĭ sān qī sì qiè]
'Living in a world full of temptations so you can have multiple partners.' Refers sarcastically to having numerous romantic or sexual partners. Historically it alludes to traditional practices where some men had many spouses. Nowadays used mostly figuratively, often disapprovingly about infidelity.
