Sang's father likes the most from Fan Zhongyan's "Preface to Different Poems of the Tang Dynasty": "Looking at the works of a virgin, she is alone and free from dust." He hopes that his daughter will not be contaminated by the dust of the world under his protection, but who knows that fate failed to protect his daughter from growing up, and Sang Jingran did not stay clean, but became alone. After rebirth, Sang's father not only lived a long life but also lived a prosperous life under his daughter's determination. Sang Jingran also relied on the advantages of reliving his life and worked hard to change, save family ties, gain friendship and love, and finally no longer be alone.
