What song is the world of mortals come and go without a trace?

Miss Chang 'an.

1, lyrics excerpt: The world of mortals comes and goes without a trace, and when you get drunk, you miss your old friend, but you can't see Wan Li for thousands of miles. There are joys and sorrows in the dream, love and hate, and clear rain.

2. Chang 'an Girl was sung by Li Changchao. "Chang 'an Girl" expresses that Chang 'an girl misses the expedition, cares about the war and looks forward to the return of the expedition. This is a very nice song.
