左手习惯有你牵右手习惯有你拉
[zuŏ shŏu xí guàn yŏu nĭ qiān yòu shŏu xí guàn yŏu nĭ lā]
Literally meaning “Left hand got used to holding you and right hand to pulling you,” this reflects the habituation to a loved one's presence and daily companionship in every detail of life, implying how integral this person is to their routine.
