Skimming the inhuman slight cold and the twelfth lunar month, I made a number.

"Pi Si" refers to the stroke structure of the Chinese character "Ba", in which "Pi" and "Si" are two basic strokes in Chinese character writing.

"Non-human" means that this number is not a word composed of herringbone, and the word "eight" is just not next to the word "person"

"Slight cold and twelfth lunar month" usually refers to the twelfth lunar month of the lunar calendar, and "slight cold" is one of the twenty-four solar terms. It may be here to make the riddle more interesting, but it has nothing to do with the answer.
