What A Letter Across Yin and Yang is about
The departed soul Shen Qinghuan works in the Yin-Yang realm for ten years to obtain a seven-day resurrection token and return to the mortal world. Yet she finds her family has seemingly forgotten her. When she is heartbroken and ready to pass on, a letter traveling between life and death reveals the truth: her family has pretended for ten years, hoping she would let go of her obsessions. She spends all her merits to trade for three more days together. But right before they take a family photo, the villain smashes her resurrection token. Finally, the family’s longing gathers to reform her spirit. She reincarnates and reunites with her loved ones once more.
