Go to the 4th floor of Meijiale Supermarket in Henan, where there is a big playground. In recent years, I have taken my sister there to play in June 1st. He had a good time, and there were indoor beaches and fishing. It's good. I suggest you go there, just opposite Han Xin's apartment.
I remember that I have been to No.44, No.45 and No.29..
Have a nice day ~!
By the way, there are many baby products on the fourth floor. You can also go shopping.
