你不是我良人怎知我情深
[nĭ bù shì wŏ liáng rén zĕn zhī wŏ qíng shēn]
This means ‘you are not my right match/true lover, how would you understand the depth of my love'. It shows that deep emotional attachment or love requires understanding from both sides. This kind of netname implies frustration at being misunderstood, particularly within romantic contexts.
