Tang Ren was originally an unknown, ordinary person, a frustrated person. When he was a child, what he envied most was his father's shiny new clothes. Later he learned that those were the clothes his father wore as a funeral director. From then on, he and his brother ostracized their father and even took pleasure in losing his father's dirty money.
After experiencing a series of twists and turns in life, and after sending away his most admired brother, Tang people finally understood that burial had nothing to do with religious beliefs, it was just a way of saying goodbye.
