"Sisters' Love" is set in Critical City, an ancient town known as "Utopia" in a coastal city. Through the legendary entrepreneurship and love stories of several generations of the Jin and Su families, it reflects the experiences of many characters from turmoil to thinking and then to success in the tide of reform. It is a shocking work that showcases the great achievements of reform and opening up. The heroine Su Duoer and the father of Su Di tried their best to break the millennium silence and avoid the obstruction of the conservative forces. They took their wives to sell critical tea to the south for the first time through tea on credit, but unexpectedly they both died. During the funeral in the south, the Su sisters' vision broadened and they determined to start a business and repay their father's debt. After a fierce struggle with Jin Erye, a representative of traditional forces, Su Duoer resolutely went to the city. Su Di also studied art by herself, and later started making clay sculpture crafts. Internet writer Xiao Junyi met Su Duoer in a chance encounter and quickly fell in love with her natural beauty. After Xiao Junyi got to know the critical city, he resolutely followed Su Duoer to start a business in the critical city. As a result, he soon discovered that Su Di was more compatible with him, and a complicated love story unfolded. However, due to their efforts, they all found more suitable positions for themselves, and everyone was happy. What is even more dramatic is that Jin Erye and Yuan Yuefen, who were infatuated with each other when they were young but struggled to live apart from each other until they were seventy years old, also had an explanation for each other, which reflected the huge motivation to emancipate their minds.
