蒙眬

zuó wǎn méng lóng zhōng wǒ hǎo xiàng tīng dào yǒu rén zài kū qì

昨晚蒙眬中我好像听到有人在哭泣。

While I was half asleep last night, I seemed to hear someone weeping.

méng lóng zhī shí

蒙眬之时

on the edge of sleep

kōng qì xī bó rì guāng méng lóng hán qì bī rén

空气稀薄，日光蒙眬，寒气逼人。

The air was thin, filled with hazy sunshine and frost.
