In the 1960s and 1970s, there was a craze for educated youth to go to the mountains and countryside. As one of the "old three", Ye Junzhi, the eldest son of the Ye family, followed the army to the northern countryside regardless of family obstruction. He fell in love with Lin Mansheng, the daughter of a local rural teacher. Later, his father rushed back to Shanghai due to illness, and Lin Mansheng gave birth to his daughter Lin Qingge alone. Twenty-two years later, Lin Mansheng came to Shanghai with her daughter to go to college and met Ye Junzhi again. Ye Junzhi is already married and has a daughter, Ye Ling'e, brought by his wife. Ye Ling'e was married to Qu Zhiyang, the second young man of Qu's enterprise, and gave birth to Qu Duole. The rectification marriage was also designed by Ye Ling'e's wishful thinking. The marriage has been shaky for three years, and Lin Qingge's addition made the situation even more complicated. The grievances of the previous generation, the emotional entanglements of this generation, the so-called happiness, is it to restrain one's sincerity and live in peace, or to be honest with each other and grow old together?
