How affordable is the trip from Nanchang to Sanya, Haikou?

I'm also from Jiangxi ~ If I travel to Sanya, I personally think it's cheaper to fly to Haikou and then travel with a group tour, because most places are led by tour guides, and the tour guides will explain them on the ground when I arrive at the tourist destination, so the price will of course be more expensive, but some tours are led by tour guides, but I think it's more reliable to travel abroad and get familiar with the local area, so it's more convenient and comfortable to choose a better package tour, but I suggest contacting the tour groups there before going. Personally, I prefer self-help tours, because shopping items can be based on my own preferences, and shopping items with group tours may be less. Both have their advantages and disadvantages. It depends on personal choice. The price difference is actually not much difference. It will be great to eat fruit in Sanya. Have a nice trip ~
