Proper Cantonese pronunciation

Proper Cantonese pronunciation (Chinese: 粵語正音運動; Jyutping: jyut6 jyu5 zing3 jam1 wan6 dung6) is a campaign in Hong Kong started from the 1980s and led by scholar Richard Ho (何文匯) to promote the "proper pronunciation" in the Cantonese language. The prescriptive nature of the campaign has led to controversies.
