What's the difference between Cantonese Opera and Cantonese Opera?

Cantonese songs are short-lived songs, just like the songs we usually listen to, but with different vocals, such as Lychee Ode and Red Candle Tears.

Cantonese opera is a big drama that people often say. Let's simply understand it as a stage play. A drama should last at least 15 minutes, such as Drunk Imperial Lady and Mu, which are relatively long dramas.
