I don't know anything about tourism and health care, but I know a little about old-age care. To tell the truth, health care and old-age care cannot be separated from eating, eating, living and traveling. Nowadays, food safety has always been a big problem, so many fruits and vegetables are under the banner of green. As for housing and transportation, it is suggested that you can choose some places with cool summer and warm winter. Of course, you can't have your cake and eat it. You can talk about life. It's summer now, like Qishan in Hunan, which is an undiscovered treasure, a national 4A scenic spot. The oxygen bar of nature has a strange mountain residence at the foot of the mountain, which is suitable for short-term and long-term living in summer. In winter, you can go to Beihai, where it's not cold. Health care is not just for the elderly. With the environmental pollution, people are increasingly pursuing the original ecology.
