After the Revolution of 1911, the Republic of China was founded. At that time, when the National Language was established in the National Assembly, the voice that Cantonese became the national language of China was quite high. At that time, Guangdong parliamentarians occupied more than half of the seats, so it should not be a problem for Cantonese to become a national language. However, considering the reunification of China, Sun Yat-sen lobbied Members one by one to use the northern dialect of China as the national language. In the end, Cantonese was defeated by one vote (one vote is three votes), and China Northern Dialect became the national language of the Republic of China.
