第七个天堂没有阳光第九个天堂只剩黑暗
[dì qī gè tiān táng méi yŏu yáng guāng dì jiŭ gè tiān táng zhĭ shèng hēi àn]
'There's no sunshine in the seventh heaven and only darkness in the ninth'. Conveys an extreme sense of despair where the normally perfect realms of existence become gloomy and devoid of any hope or joy.
