我念她不在这个冬天我想他不在那个夏天
[wŏ niàn tā bù zài zhè gè dōng tiān wŏ xiăng tā bù zài nèi gè xià tiān]
This translates to 'I Think of Her Not Here in This Winter' or 'I Think of Him Not Here in That Summer.' It describes a nostalgic yearning for someone who was present in certain seasons of the year but now absent, creating feelings of loneliness and longing.
