烂人烂心乱花心好人好心没良心
[làn rén làn xīn luàn huā xīn hăo rén hăo xīn méi liáng xīn]
This translates as 'bad person with a bad heart who loves irresponsibly; good person with a kind heart lacks conscience.' It suggests the owner’s understanding that not all good-looking people have good intentions, nor are all plain-looking people necessarily kind-hearted. It's somewhat contradictory and expresses frustration.
