与其抱头痛哭不如强颜欢笑
[yŭ qí bào tóu tòng kū bù rú qiáng yán huān xiào]
Rather than indulge in mutual tears when suffering from difficulties, one chooses a mask of happiness and maintains an optimistic exterior despite interior hardship. This reflects a mentality preferring strength over showing vulnerability, a way to cope with pain and sadness by adopting a more cheerful façade.
