The Chinese word "布什" is formed through phonetic transliteration, specifically to represent the English surname "Bush". The character "布" (bù) approximates the sound "Bu", and "什" (shí) approximates "shi", together creating the pronunciation "Bùshí", which closely matches the original name's auditory profile. This method selects characters based primarily on their sound rather than meaning, resulting in a compound that serves as a sound-based equivalent for the foreign term.
