1. 唔該 (m̀h goi): This is the most common and versatile way to express gratitude. It's similar to "thank you" in English and can be used in most situations.
2. 多謝 (dōh ze): This is a more formal and polite way to say "thank you." It's often used in situations where you want to show extra respect, such as thanking someone for a gift or a favor.
Here are the characters for each:
* 唔該: 唔 (m̀h) + 該 (goi)
* 多謝: 多 (dōh) + 謝 (ze)
Remember, even though the characters are the same, the pronunciation varies slightly depending on the context.
