Mao Zedong
Mao Zedong also made several changes to the Chinese language, such as switching from the Wade-Giles system of Romanization to Pinyin. For this reason, Nanking is now called Nanjing on modern maps. Taiwan still uses Wade-Giles, so its capital is called Taipei instead of the pinyin Taibei. Mao also simplified the Chinese characters. In theory it would make them easier to read and write so that more people would be literate.
