In the observation of the world's cavity, urban men and women satisfy their vanity or improve themselves by pretending. Pretending refers to showing a temperament that you don't have in order to gain psychological satisfaction or even deceive others. There is both a negative side to this behavior and a positive side – as Tang Ying puts it, "fakeittillyoumakeit", that is, pretending to have it until it really has. Whether you are sophisticated or confident or not, you can gradually achieve real change through deliberate performance.
