The Chinese word 阿姆斯特朗 is formed through phonetic transliteration of the English name "Armstrong", with each character representing a syllable: 阿 (ā) for "Ar", 姆 (mǔ) for "ms", 斯 (sī) for "s", 特 (tè) for "t", and 朗 (lǎng) for "rong", using characters chosen solely for their sound approximation without regard to their individual meanings.
