What's the matter with "Lingniao contains books"?

This is fake. Birds are trained, and most of the signatures contain organs. Some of them hide the millet that birds like to eat in the brand, while others put some flavors that birds like on the brand. The fortune-teller kept the bird in a cage, then fiddled with the sign while people were unprepared, and then let the bird out to draw lots. The bird will naturally draw the corresponding constellation according to the fortune teller's wishes, which has been exposed on TV ~
