Cantonese Opera (also known as "Guangdong Drama") is the main drama class in the Guangdong area. Cantonese Opera was prevalent in Guangxi, Hong Kong and Macau. Cantonese Opera has included other Chinese drama like Yick Yeung Pitch and Kwan Pitch etc.
At the end of Qing Dynasty, the Guangzhau dialect was used in Cantonese Opera because the cultured people wanted to make use of Cantonese Opera as propaganda for voicing revolution . In order to make Guangzhau people understand more easily, lots of Cantonese was used. In the early stage, performances were mostly arranged in the opera bamboo-sheds where God statues and altars were placed for worship. Hong Kong opera bamboo-sheds mostly have Ritual Performances to celebrate birthdays of deities and Buddha. These performances allow devotees to worship and thank them.
Cantonese Opera are extremely attractive,you need to take a look if you're stay in Hong Kong.Thanks.
