小男人有点不淡定小女人有点不矜持
[xiăo nán rén yŏu diăn bù dàn dìng xiăo nǚ rén yŏu diăn bù jīn chí]
Describing personality traits of both genders, it translates roughly to 'The little man lacks composure and the little woman lacks reserve.' It suggests that despite appearing less mature or composed, there is mutual honesty and perhaps boldness in expressing feelings between these two.
