More than 20 years ago, Tang Guanzhong and Cheng Shi gave birth to children at the same time. Cheng Shi and his wife were forced to fall off a cliff and died, resulting in the misplacement of the identities of the two children. Tang Zheng (played by Xie Jiajian) became the eldest son of Tang Guanzhong, the owner of the "Wanjiaxiang" small restaurant, while Tang's biological daughter Cheng Xi (played by Qi Wei) became the daughter of Shanshui Group. Many years later, Tang Zheng and Cheng Xi met and fell in love with each other. Cheng Chaoqun (played by Zhang Danfeng), the elder brother who always believed that Cheng Xi was an adopted daughter, expressed his love to Cheng Xi. Cheng Xi's refusal made him point the finger at the Tang family. In addition, the old enemies Tian Zaitian and Zeng Congming continued to create obstacles, and the road to cooperation between the two families was full of crises. The mystery of Tang Zheng and Cheng Xi's life experience was gradually revealed. On the other hand, Tang Li (played by Chen He), the son of the Tang family, fell in love with Tian Xin (played by Reyiza), the frail and sick daughter of Tian Zaitian. Although he was opposed by his family, he remained steadfast. Tang Tang (Lou Yixiao), the daughter of the Tang family, has a crush on Cheng Chaoqun. She knows that she is being used but still loves him. In the end, she moves Chaoqun with her pure kindness. When love conflicts with family affection, conspiracy and desire intertwine, the destined love finally mixes the most delicious recipe for life...
