If you are in the south, such as Guangzhou and Shenzhen, you can choose to go on a road trip to the Yangmeikeng Valley in Shenzhen (a sandy beach with only crystal clear, blue-green water). Very rare. I've been there once in a while before and will never forget it. This place feels like paradise, but there are too many people and too much traffic during the holidays. Going in off-season is definitely the best. Go to Shantou, Chaozhou, feel the flavor of the ancient town, you can eat and play, all the way. Don't say how happy this feeling is; or you can go camping, climbing mountains and so on. In Qingyuan, Shaoguan and other places. These are great places for parents and children to vacation. In winter, of course, you can also choose to go to hot springs. In Qingyuan, there are rumors of geothermal hot springs, but such wild ones need to be looked for carefully.
I don't think traveling is fun. What matters is who you go with and who you hang out with. In fact, the atmosphere is so important that a simple hike can be a little more fun.
