A 30-year-old Chinese girl stands in a magnificent beauty salon, her lips curved upwards, revealing a gentle smile. She has elegant manners and extraordinary temperament, as if there is a hint of tranquility in this busy city. I am holding a wine red cola thermos in my hand, with a silver rim on both the lid and bottom. The paint on the cup body is shiny, and the words "Crazy cola" are written vertically on the cup.
