正点西施
[zhèng diăn xī shī]
Xishi is often seen as the archetype for Chinese classic beauty, much as Mona Lisa does in Western culture. Adding 'correct time,' this nickname seems to suggest that the person can match up to Xishi's standards or be a present-day representation of timeless beauty. However, '正点'(correct time) might have another slang meaning in youth language which means perfect or exactly, implying she/they is/are the best beauty.
