人间妆红
[rén jiān zhuāng hóng]
Roughly translating to 'human world makeup red', possibly signifying dressing up in bright colors to express joy in life or draw attention; adding vivid touches of makeup or attire in living a worldly or social human life. But it can also be related to 'red makeups' used by Peking Opera actors or actresses who play the part of a villain.
