Choosing the right greeting:
The best way to choose the right greeting is to consider your relationship with the person you're addressing and the situation. It's always better to err on the side of formality, especially if you're unsure.
Remember that Taiwanese is a tonal language, so the pronunciation of each word is important. It's best to practice saying these greetings with a native speaker or a language learning app.
