I found Yu in Chengdu, but after talking to him, I found that I couldn't go back to Old Chang 'an. What happened?

After the west gate of Guangdu Town enters, there will be a conversation with him on the right near the entrance of the prestigious area.

The option of returning to the hometown of the Tang Dynasty (described in this way) is the descriptive option of the old Luoyang, the old Chang 'an, the old Tiance and the old Weathering Valley after the opening. Just click on it. If it can't be transmitted, try twice. If it still doesn't work, there may be a bug in the game.
