Jiang Xinyu in the urban area is also very distinctive.
You can go to Jiang Xinyu first. There are Jiang Xinyu Oriental Park and Xiyuan Park. If you don't want to go to a water park or something, just go to Dongyuan Park, which is more cultural than calling it.
Then you can take the ferry or the Third Oujiang Bridge to Yongjia Oubei, and then drive all the way. There will be many scenic spots. You can ask people on the side of the road.
Then you can play all day, go back to the city at night or stay in Oubei.
