The pinyin of Moutai's trademark "MOUTAI" is the Weituma style pinyin. It has been like this since the brand Moutai came into being. After the promulgation of my country's Modern Chinese Pinyin Plan in 1958, the country required the use of standardized Chinese Pinyin. However, considering that Moutai's trademark "MOUTAI" has already formed a brand in foreign markets, in order to avoid changing the trademark and causing inconvenience to foreign consumers, it was not changed. This trademark also complies with relevant national regulations. Similar ones include Zhonghua cigarette "Chunghwa" and Changyu wine "Changyu".
