慢慢学坏才能让自己变好
[màn màn xué huài cái néng ràng zì jĭ biàn hăo]
Learn to be bad little by little to improve oneself. In this context, 'learn to be bad' may mean learning to accept oneself fully, including weaknesses and imperfections, in order to eventually grow into a better version of oneself. It reflects the journey toward maturity and accepting various facets of oneself instead of always adhering to strict good behavior.
