My brother bought a house for my parents in Kangyuan Health Valley some time ago. I think it is quite suitable for the elderly to live for a long time. First of all, the environment and lighting are good, and the greening of the community is also very good. There are supermarkets, subways and bus stops nearby, which are very convenient for travel or shopping and close to the hospital. There is also a green channel for first aid, which is also very convenient for seeing a doctor. If you want to know more, you may wish to check Baidu.
