In the past, you were called Chang'an and I was called hometown.
There is no hometown at the end of Chang'an, and my hometown will no longer be in Chang'an.
Now my name is Chang'an and you call me hometown.
The leaves in Chang'an are falling like my hometown, and the flowers in my hometown are blooming in memory of Chang'an.
Intention: When spring comes back from my hometown, the leaves fall and I remember Chang'an.
