How much does it cost to travel from Nanchang to Hangzhou? Double, preferably two days and one night or three days and two nights.

Take the elderly to Qiandao Lake for two days. Qiandao Lake has good air, which is very suitable for the elderly to keep healthy. They eat and live in Shanwanwan Farm. If the elderly don't want to visit scenic spots, they can take them around the lake around the farm, climb fruit orchards and go fishing. It doesn't cost much. If it costs two days and one night, the tickets and accommodation will probably be around 3 yuan alone.
