深知我者久居我心深爱我者久伴我身
[shēn zhī wŏ zhĕ jiŭ jū wŏ xīn shēn ài wŏ zhĕ jiŭ bàn wŏ shēn]
The meaning is that the one who understands me truly resides deep in my heart; those who deeply love me will stay with me for a long time. It refers to the people who genuinely understand you remaining close, and those who cherish you always by your side: 'True understanding brings someone closer in one's heart; True affection makes them constantly stay beside the beloved one.'
