望着天空好咸嗯有泪在里面
[wàng zhe tiān kōng hăo xián ng4 yŏu lèi zài lĭ miàn]
Translating to 'Looking at the sky tastes salty, yes, there are tears inside', it's a poetic expression for expressing sadness or sorrow. The sky tasting salty metaphorically implies that one might be crying and not realize it, making this a very emotive and expressive username.
