My wife is also from Zhongshan. I would like to briefly recommend some tourist destinations in Guangdong Province for your reference. I hope it will help. After three days, there are still many choices. Conghua: Shimen Forest Park, Liuxihe Forest Park (these two forest parks have beautiful scenery and flowers), Tianshi Cherry Blossom Paradise (mainly looking at cherry blossoms) and Xitou Village; Huadu: Huadu Vanilla World, Baosang Garden (where mulberries can be picked), European Town of Jiulong Lake (European-style architecture, excellent photo spots) and Hongshan Village; Zengcheng: Menghuabu Village in Zhengguo Town and Huxin Island Scenic Area (with good scenery along the road and delicious Zhengguo Wonton), which can be combined with Huizhou Nankun Mountain; Nansha: Million Sunflower Garden, Nansha Wetland, Waterbird World, Jiujiuyong; Foshan: Lingnan Xintiandi, Zumiao and Liangyuan; Shunde: Qinghui Garden, Fengjian Water Town and Changlu Farm; Huizhou: Luofu Mountain, Hastate Town of Minmetals, West Lake, Honghua Lake, xunliao bay, Shuangyue Bay and Daya Bay; Shenzhen: East OCT Chaxi Valley, Big and Small Meisha, Jiaochangwei, Xichong, Guanlan Printmaking Village and Gankeng Hakka Town; Zhaoqing: Qixingyan, Dinghushan and Guangning Bamboo Sea; Jiangmen Xinhui: Guifeng Mountain, birds of paradise and Chenpi Village; Zhuhai: Shijingshan Park and Chimelong Ocean Kingdom, or you can take a boat trip to Dong &;ao Island, Wailingding Island and Dangan Island at Xiangzhou Port Passenger Terminal. Seeing the sea from the outer islands is much more beautiful than the land and coastal beaches. In addition, the commercialization of Yuanming New Park is very serious after free admission.
