According to legend, the demon spirit is immortal, heartless, without love, and has neither laughter nor tears. There are seven emotions and six desires, but the first thing he taught him was sadness. Cry without sound, be sad without tears. The world of mortals is vast, the music and songs are prosperous, and the passing years are like sand on the fingertips. I have been searching for you for thousands of years, just to give you a drop of clear tears. That touch of green shirt is lonely and prosperous. The name "Luo" has been remembered for thousands of years and forgotten for thousands of years.
