Tian Tongzhi, a scholar in Qing Dynasty, mentioned the concept of "one person acting as a boudoir" in Xipu Ci. Boudoir here does not refer to a woman's voice, but refers to the style and artistic conception of words. Comrade Tian believes that the part of the word "one person as a boudoir" will suddenly lead to the sadness of parting, while the part that sings things will all contain the hate of abandoning donations. Even if there is no real thing, there will be deep feelings in it, which makes people feel that their soul is heartbroken and flying.
