Significado
Asking for the reason behind something.
Contexto cultural
Asking 'why' can sometimes be seen as intrusive. It's often better to wait for the person to volunteer information unless you are close friends. People in the South are generally more direct and use 'vậy' almost exclusively. It sounds friendly and open. Northerners often use 'thế' instead of 'vậy'. It can sound a bit more formal or traditional to Southern ears. Young people often shorten it to just 'Sao?' or use slang like 'Ủa sao vậy?' to express sudden shock.
The 'Ạ' Rule
Always add 'ạ' at the end when asking an elder. 'Tại sao vậy ạ?' sounds 100% better.
Don't be too aggressive
If you repeat 'Tại sao vậy?' too many times, it can sound like you are interrogating someone. Mix it up with 'Kể mình nghe với' (Tell me about it).
