The terrier of 80 yuan forgetting to change the ****shared bicycle refers to the fact that in Chengdu, some people spend 80 yuan to hire a sign-raising water army, while they themselves rent a ****shared bicycle to come to the scene, and then forget to return it. This is used to mock those who contribute but lose money. This terrier is also satirizing certain social phenomena, such as the value of labor being deducted.
