Here's how to pronounce it:
* zou2 - Sounds similar to "joe" but with a slightly higher tone.
* san4 - Sounds similar to "sun" but with a slightly lower tone.
You can also use 早 (zou2) on its own as a more casual greeting for "good morning."
Remember that Cantonese tones are crucial for understanding the meaning of words. It's best to listen to a native speaker or use a pronunciation guide that includes tone markings to get the correct pronunciation.
