枉我一世倾城
[wăng wŏ yī shì qīng chéng]
'Wang Wo Yishi Qingcheng', translates into 'All My Life Was in Vain To Become The Beauty That Could Make a City Weep'. According to legend, if a woman is exceedingly beautiful, when she passes by a city it is said that the people will stop everything to admire her beauty which causes the guards on the wall to abandon their posts, leading to tears for the lost vigilance and hence 'beauty to make a city weep'. Therefore, using this as a username means that despite her remarkable charm, it is all for nothing.
