In the early days of reform and opening up, Su Lan, an educated youth who went to the countryside, chose to take root in the remote Qingshan Forest Farm, and became a capable forest farm technician from an ignorant girl. Once when she went back to her hometown to visit relatives, her cheerful temperament and thick eyebrows and big eyes attracted her fellow countryman Chen Zhiqiang. His passionate pursuit and persistent offensive made her fall in love next to the forest cabin in the forest farm. The two soon fell in love, but unexpectedly received the news of pregnancy.
However, this sweetness suddenly turned into thunder - Su Lan unexpectedly learned that Chen Zhiqiang had already been married and had two daughters. In order to avoid being punished for style issues, Chen Zhiqiang coaxed his ex-wife Liu Mei into a divorce, and eventually married her hastily with Su Lan as her unborn child. After getting married, Chen Zhiqiang's nature was hard to change and he was still merciful. After the birth of his daughter Su Xiaoqing, Su Lan, who was completely disappointed, decided to return to the forest farm with her infant child and live in a small cubicle of ten square meters.
In the following decades, Su Lan gave up remarriage and relied on the forest farm's meager income and tenacity to raise Su Xiaoqing alone with the care of the old farm director Zhou Jianguo and the help of her friend Li Juan. After her daughter became an adult, she met the down-to-earth and reliable Gao Lei and formed a happy family. In the end, during the quiet years in the forest farm, Su Lan watched her daughter and son-in-law live in harmony and love, with her grandson around her knees. All the hardships in the past turned into the gift of stability and contentment in her later years.
