I bought the "Lucky Golden Ball" at Yiwu Jewelry Store. According to the staff in the store, "Lucky Golden Ball" is actually a red rope with a golden ball on it, which means auspiciousness, auspiciousness, perfection and "ball". Some people used to buy this kind of "golden ball for good luck", but the sales volume was very limited. I found that Olympic champions also like to eat.
I hope it helps you.
