Is the poem in the cartoon "Everything has Poetry" written by the children themselves?

Yes, UnionPay poems and POS poems are the works of mountain children. Many pictures in Everything has Poetry are "spelled" by children's poems in the mountains. As the picture changes, you can read different children's poems. These left-behind children in the mountains have unlimited talents to be discovered, and they have the simplest and most sincere feelings to talk to the world. The poems of UnionPay POS machines are the most sincere and touching feelings of children. This activity made people see the talents of mountain children, and at the same time, it also received enthusiastic participation from all walks of life. I hope my answer can solve your problem.
