这个是单眼皮这个是双眼皮
[zhè gè shì dān yăn pí zhè gè shì shuāng yăn pí]
This literally translates to 'this one has single eyelids and this one has double eyelids', a self-deprecating joke that points out physical characteristics which are usually inherited. Single vs. double eyelids are distinguishing facial features common in discussions about East Asian aesthetics.
