少年你长得阳光清秀菇凉你长得倾国倾城
[shăo nián nĭ zhăng dé yáng guāng qīng xiù gū liáng nĭ zhăng dé qīng guó qīng chéng]
This nickname contrasts the charm of a young boy, described as having a sunny and fresh appearance with that of a girl, who is compared to someone of astonishing beauty. '倾国倾城' originally means so beautiful that she can make the whole country fall, implying an extraordinarily charming and elegant woman.
