Which is the biggest park in Shaoyang?

First of all, I'm from Shaoyang, Shaoyang. At present, there are Shuangqing Park, Beita Park, Dongta Park, Times Park, Wei Zi Park and Chengnan Park in the urban area! There is Songpo Park in the suburbs. Of course, there are other interesting places, most of which are Stone Village, Jinshan Lake Resort, bottomless pit, Baishui Cave and Peach Blossom Island in the suburbs. . . . In addition, what are the world-famous Langshan, Cai E's former residence, Wei Yuan's former residence and He Lvting's former residence in Xinning County? Ask for adoption!
