Chinese not only use numbers to appeal for good fortune, they also bring them out to chew people out: "You 250 [fool], you do things neither three nor four [without any order or out of touch], and still you dare to say that I'm 13 points [stupid] and 3-8 [scatterbrained]."
中國人不但拿數字來「呈祥」，還拿它來罵人：你這「二百五」，做起事「不三不四」，還敢說我「十三點」和「三八」？
