Let me give you a general idea. The average weight of Chinese athletes is about 4000 yuan per year. The prices of different stores are not the same, and the jade bird is roughly the same. Haosha is cheaper, and the cheapest year is only 900 yuan. There are cheaper ones, such as some community fitness clubs, which only cost 400+ a year. But it's roughly a penny. It's expensive for a reason.
There is also convenient transportation, and it is best to be close to home. Some shops are very good, but it takes several hours to go back and forth on the road every day, which is obviously not suitable. This fee should also be included.
I wish you can find the one that suits you!
