His eyes snap open, at that, and he fixes Wei Ying with a flat glare before shaking his head, resigned.

He draws a deep breath, and begins to sing, soft but clear:

wén dí sheng dú chóu chàng
yún shēn yè wèi yāng
shì yǔ fēi dōu guò wǎng
xǐng lái le zěn néng dāng mèng yī cháng...

(Listen for the melody of a flute, alone in sorrow)
The nights in the clouds are long
Once together, now it’s all in the past
In wakefulness, how can I brush everything away as a dream?)
