Where do you think is the best place for northerners to provide for the aged?

If you ask me, I'll order Panzhihua. Reason: Fruits at 26 degrees north latitude include fruits from the south and the north. The large temperature difference between day and night and abundant sunshine make the fruit quality here superior to other areas. Up to 2600 hours of sunshine every year. There is little rain and no wind, but the air is moist. Convenient transportation, more than 200 kilometers from Kunming, more than 200 kilometers from Xichang and more than 400 kilometers from Chengdu, with airports, highways and railways. The average temperature is 26 degrees, which belongs to subtropical climate.
