[Father and Son Reborn] Missing Chang'an

I have traveled thousands of miles alone and never felt lonely. It was only after arriving in Chang'an that I began to feel lonely. There is a city of Chang'an in everyone's heart. It took me a lifetime to figure out that I had never been there. I have always wanted to write a story about Lang'er who is unwilling to be entangled with his father after his rebirth. Yes, it is entangled. When I saw this paragraph in Hetu's "Not Seeing Chang'an", I felt it was very similar to Lang'er's state of mind, so I came up with this title. "You can see the sun but not Chang'an." Chang'an in Lang'er's heart is his father! But his father never took him there. T0T
