Years ago, Li Xiuqin adopted Li Tiantian, who had been abandoned by his biological parents, beside a garbage dump. However, Li Tiantian was born with leukemia. Li Xiuqin worked three jobs a day and donated her own bone marrow to successfully save him. Li Tiantian was also very filial. Twenty years later, he returned having completed his studies, but his biological parents, Zhang Ai and Xu Tianci, sought him out, wanting Li Tiantian to return to his ancestors' fold solely to acquire the heirloom of Li Tiantian's grandmother. The biological parents used Li Tiantian's future to threaten Li Xiuqin, making her admit that she was a human trafficker. Because of this, Li Tiantian misunderstood Li Xiuqin and stood by idly while his family abused Li Xiuqin, little knowing that Li Xiuqin had already contracted cancer and was about to die.
