Where can I buy a treadmill in Cangxi, Guangyuan

I don't think so. Visit the five-star garden, or look at the electric supermarket in the square.

I suggest you don't buy it in Cangxi. First, it is expensive. For a long time, there are few businesses, if any, there are only a few, and there is little choice. At the same time, the quality of what you buy is not necessarily good.

Go to Guangyuan or Nanchong and ask the acquaintances there!
