I know about Cheng huaijin

Gu Xin and Xie Zhiyi stayed in chunnan city until early November. They only planned to return to kun city when Gu si and Huo Yanyu arrived.

The Grand Empress Dowager looked at her sisters and said with a smile, " "This old woman has caused you to suffer. How about I go back with you?"

Gu Xin held the Empress Dowager's hand and said, " great-grandma, aunt Huan is coming to pick you up. We'll go to the goddess Kingdom in a few days. The weather in the goddess country is also very good. You can go and see the scenery that is completely different from that of great Zhou!"

The Empress Dowager smiled helplessly,"you!" Are you going to bring great-grandma out to sea to play when you can sail in the future?"

Gu Xin nodded without hesitation, " of course! He definitely had to take great-grandma to the sea to play. Of course, he had to be prepared to make sure nothing went wrong. Great-grandma, you must go out and play happily."
