It is cheaper to sell dumbbells in Yangzhou or Qujiang small commodity market. I remember that two people who bought 20 kg before cost more than 30 yuan. Now it is estimated that it will be more than 40 yuan at most. You can ask around more. People in the flower and bird market are idiots. Take one when you see one. If I buy it on Taobao, the freight is also expensive. I will go by car on Saturday and Sunday. If I still buy it, I will definitely go to Qujiang to buy it.
