山有木兮木有枝山悦君兮君不知
[shān yŏu mù xī mù yŏu zhī shān yuè jūn xī jūn bù zhī]
This name quotes a famous love poem. It's describing someone's feelings toward another, saying that just like how mountains nurture trees and how tree branches grow, my feelings for you come naturally, yet they're unknown or unreciprocated from your side. It's filled with subtle and deep yearning.
