Xia Zhi, an ordinary copywriter who has been struggling in an urban advertising company for five years. Her life is like a programmed program: she is woken up by the alarm clock at seven in the morning, takes an hour to get to the office on the subway, goes to the computer to revise advertising slogans that she does not believe in, and drags her exhausted body back to the rented single room at nine in the evening. The change happened late at night when she was working overtime. She found a comment under the promotional copy she wrote, "This ad is really bad, but I bought it anyway because I urgently needed it." At that moment, Xia Zhi stared at the screen, feeling sour in his stomach. She suddenly wanted to write something real, even if no one read it. So she registered a blog that no one knew about and began to record the real moments of ordinary people that were hidden by advertising slogans.
