客官小女子只卖身不卖艺
[kè guān xiăo nǚ zi zhĭ mài shēn bù mài yì]
This phrase means 'Dear customer, this humble woman only sells appearance, not talent'. It's an ironic or self-deprecating statement often associated with traditional entertainers or performers who offered more than just artistic performances, suggesting someone who focuses on looks rather than skill. Nowadays, it can have humorous or exaggerated tones.
