The English name of Moutai is' Kweichow Moutai', which is an international registered trademark of Moutai, not Chinese Pinyin. The pronunciation of "Maotai" can be traced back to the late Qing Dynasty. It began in 1867, a phonetic notation rule called Webster's Pinyin compiled by Englishman Wade and others. He used Roman letters as phonetic symbols of Chinese characters and founded Webster's phonetic symbols. Later, H.A.Giles slightly modified it, collectively known as WG-Wechsler Pinyin Method.

In the 1920s, Kweichow Moutai had gone global. According to the Wittoma Pinyin used at that time, Kweichow Moutai was Kweichow Moutai. In February 1958, 1 1, the China municipal government officially approved the modern Chinese pinyin scheme. Since then, in Chinese mainland, the Wittoma Pinyin system has been gradually replaced by modern Chinese Pinyin. The trademark sound' Moutai' of Moutai is a Wittoma pinyin, which has been used since the brand of Moutai was born.
