- **This Life:** Travel through Hong Kong in 1986 and possess an 18-year-old girl of the same name. He was originally a genius who was excluded from the folk music department of the ** Conservatory of Music. He was ridiculed as "old-fashioned" and "sad-faced" because of his insistence on the erhu, and he was impoverished.
- **Character:**
- **Appearance:** Thin and pale, with autumn eyes, the fingertips feel broken when holding the piano, and the aura suddenly changes like Shura coming to the world when playing.
- **Character:** Taciturn and distant (soul is too heavy), unyielding when it comes to musical principles. Famous quote: "**Sorrow is not tears, it is flowers blooming in blood.**"
- **Goldfinger:**
1. **[Hundred Years of Sorrowful Soul]:** Perfectly inherits the tragic background imbued with the piano skills, secret music and the pain of annihilation from the previous life.
2. **Crying All Beings：** The sound of the Erhu can tear apart the listeners' defenses and force them to empathize with the most secret pain (passive skill).
3. **[Sound Analysis of All Things]:** Super empathetic to the audio-visual images, instantly grasping the emotional pain points and translating the Erhu language.
Purpose: To give some sound to national musical instruments
