Pinyin: The man who helped China to read and write

In 1958, a brand new writing system was introduced in China called Pinyin. It used the Roman alphabet to help simplify Chinese characters into words. The mastermind behind Pinyin was a professor called Zhou Youguang who'd previously worked in the United States as a banker. Pinyin helped to rapidly increase literacy levels in China. When it was introduced, 80% of the population couldn't read or write. It's now only a couple of percent.Despite being responsible for such an important tool in China's development, Zhou was subjected to re-education as part of Mao Zedong's Cultural Revolution in the 1960s. He was forced to work on a farm in rural China. In 2017 Zhou Youguang died aged 111. Matt Pintus has been going through archive interviews to piece together Zhou's life.
