Well, it is based on the day when the monkey arrives at the three-star cave of the oblique moon.

This year, the monkey came to this world for eleven years, the finch died for ten years, and the exact age of the wind chime is more than eight years old. (The article mentions that the wind chimes are around ten years old in this section, not that the wind chimes are just ten years old.) After the monkey apprenticeship was successful and he stayed in the three-star cave of the oblique moon for more than a year, he mentioned that "the wind chimes are just a ten-year-old child." ”）

It is hereby clarified.
