The traffic jam and poor air quality in the core city of Guangzhou are not suitable for the elderly to live in. I suggest you consider the areas around Guangzhou, such as Panyu, Conghua and Zengcheng, which will be better and the house prices will not be so high. A friend bought a house for his parents in the Royal View of Liuxi, Conghua. I went to see this house, which is next to Liuxi River. The scenery is pleasant and the air is fresh. Very suitable for the elderly to live in. You might as well think about it.
