How do Guan Ju's poems express the bitterness and joy in love?

The content of Guanju is very simple. It's about a gentleman's pursuit of a lady. If he doesn't get a lady, he will be upset and can't sleep over and over. I was very happy when I got a "lady". I invited people to play music to celebrate and make the "lady" happy.

It turned out to be a wedding song, which was praised by the man's family and wished the bride a happy marriage. It is also appropriate to regard Guan Ju as a wedding song, from My Fair Lady, My Gentleman is Good, to Friends of Bunny Bunny and Music of Bells and Drums.
