What season is suitable for the elderly to travel?

For the elderly, I think any season is suitable. There is a summer place and a warm place in winter, so the suitability depends mainly on the tourist places.

If it is summer, it is recommended that the weather is cool and suitable for summer vacation, such as Dali in Yunnan, Lijiang, Enshi in Hubei and Shizhu Huangshan Scenic Area in Chongqing.

If it is winter, I would recommend Sanya in Hainan, Lianyungang in Jiangsu and Xiamen in Fujian.
