Despite her parents being trashy and selfish, she still tried to understand them and thought of their happiness. In all honesty, I don't really get why Mao could still forgive her parents... The mother left her daughter selfishly breaking the family, the father gave up being a father the moment he just handed her over to someone else, even if it's someone they knew for a long time... But that's not all they did. Since young Mao has been severely neglected.
