皇后要母仪天下皇上臣妾做不到
[huáng hòu yào mŭ yí tiān xià huáng shàng chén qiè zuò bù dào]
In imperial China, 皇后(Queen Mother) had to behave so virtuous as 母仪天下(a model mother for the entire country), whereas the emperor’s concubines would not be held to these high expectations. So if the holder is female, this username shows she doesn’t want to follow traditional moral restraints and norms; while if the holder is male, it may mean he is unwilling to play an important but onerous leadership role
