初见红脸再见红眼
[chū jiàn hóng liăn zài jiàn hóng yăn]
'Blushing at First Sight and Meeting Again With Red Eyes'. This phrase paints a scene where blushing happens during first meetings (often because of nervousness/shyness) and red eyes indicate sadness or fatigue seen in the next encounter with the same person or similar occasions.
