Li Shuping, a little woman walking alone on the road of life, is kind and simple, with a heart that longs for plainness and pursues happiness, but this heart has nowhere to rest. When her husband took over the baton from her father, she thought she had been liberated and found happiness, but she didn't want to be sent to another prison. Faced with the fight between mother-in-law and daughter-in-law, and the friction between husband and wife, Li Shuping had no ability to fight back, or in other words, no intention to fight back. This heart had been tightly bound by his father when he was a child. He was used to being bound, so he had no resistance. In her eyes, life is always a mess, and she can't figure it out or explain why. Therefore, she can only bump around and bruise herself. Sometimes, she is tougher than others and can endure more hardships; sometimes, she is timid than others and dare not grasp happiness when it comes. Just like her name "Ping", she has been drifting from day to day like duckweed.
