It was one of those midnight musings, so common during adulthood, when the regrets and triumphs of our lives become vibrant characters dancing in our minds. Liu Fang wrote a simple statement on Weibo that read: “What I regret most in my life is getting married and having a kid. How wonderful to just be alone!” Her post captured an increasingly common reality in China, where many people, primarily women, are questioning the institution of marriage itself. Liu, 38, has been married for seven years and has a six-year-old son. When she first got married, she expected her happiness to be doubled and her sorrow halved, she said in an interview.
