The day he left Chang'an City, the sky was filled with yellow sand, the long flags were blown loudly, and the ancient city gates were majestic and golden under the scorching sun.
The little girl's crisp and sweet voice came from beside her, "Brother, what are you looking at?"
"Nothing, let's go."
On the day he returned to Chang'an City, there were wild geese flying overhead in the sky, and the city walls were still the same as when he left.
Ten years apart.
