The ex-girlfriend sent a dynamic phone call "Chang 'an goes back to his hometown, and Chang 'an is in his hometown". What does that mean?

One is called Chang 'an and the other is called hometown. Chang 'an belongs to his hometown, and his hometown belongs to Chang 'an.

The expression "Chang 'an is hometown" often appears in ancient poems, so netizens wrote a paragraph "From now on, my name is Chang 'an, and you are called hometown, because Chang 'an belongs to hometown, and hometown has Chang 'an". Use homesickness to express your feelings, that is, you have me and I have you, and I hope to be together forever and never part.
