山有木兮木有根心悦君兮君卟知
[shān yŏu mù xī mù yŏu gēn xīn yuè jūn xī jūn bŭ zhī]
This line is derived from an ancient Chinese poem. In English, it roughly translates to 'The mountain shelters trees, and the tree stands on its root; I am fond of you, but you do not know.' Here, it reflects a deep admiration and unrequited affection where the speaker’s love remains unnoticed by the beloved one.
