唱白脸 Wear the white mask of the villain
【注音】chàng bái liǎn
【解释】你如果看过京剧的话，一定注意到了，“坏人”往往化妆成白脸。所以“唱白脸”表示对人及其严厉苛刻。（常与“唱红脸”一起用，见“唱红脸”）
If you’ve ever seen a Beijing Opera, you’ll surely notice that “villains”would always wear a white make-up. So this expression means you pretend to be harsh and severe. (often used in contrast to “wear the red mask of a hero”, see chang hong lian)
【例子】
例：在我们家，教育孩子的时候我唱白脸。
Ex.：In my family, I’ll play the harsh guy in educating our child.
