This new object has never been seen before and attracted the attention of many passers-by.

It turns out that this kind of "colorful balloon" is called bobo ball, which is very eye-catching and deeply sought after by young people.

It is said that this kind of lamp generally costs 30-35 yuan in the streets of Jinan, but the cost is only seven or eight yuan. You can earn more than 20 yuan each time you sell a balloon, and the profit is huge!

A young man who sells balls said that sometimes he can earn thousands of dollars a night.
