山有木兮木有枝心悦君兮君有知
[shān yŏu mù xī mù yŏu zhī xīn yuè jūn xī jūn yŏu zhī]
These lyrics are adapted from an ancient Chinese folk song. In English, it would roughly mean 'The mountain has trees, and the tree has branches; my heart loves you, and I hope you know it.' It implies a declaration of love with the beauty of nature as its metaphor.
