The word "伙伴" (huǒbàn), meaning "companion" or "partner", originates from a vivid historical practice. It is formed from "火" (fire) and "伴" (companion), directly reflecting its original meaning: in ancient times, particularly among soldiers or travelers, individuals who shared the same cooking fire for meals were bound together in a practical community. This shared necessity of gathering around a single fire for warmth and sustenance naturally fostered a close, cooperative relationship, thus the term came to symbolize those who share in life's basic routines and endeavors as trusted comrades.
