An animation based on reality. Maomao lives in an era when Coca-Cola is deeply rooted in people's hearts. This drink is not just a drink here. Behind it is the powerful economic and cultural background of the West. It represents the characteristics of this era very well. The materials of the "Beijing City" she built herself include old tiles from old houses that are about to be demolished, as well as scattered small toys, Chinese lucky cats and foreign "Garfield" that is well-known in China, many Coke cans, and Erguotou bottles, which represent the preferences of a specific group in China, and this is a large group. Maomao's summer records the development of the times, the growth of the city of Beijing, and the changes in people's perspectives in this era that are unconsciously and involuntarily changing.
