Answer

'Why do you learn Mandarin?'
This is correct.

'Why you learn Mandarin?'
This is incorrect. If you said this, people would understand you, but it sounds like 'pidgin English', or something that very small child might say.

'I don't know why you learn Mandarin.'
This is the correct form. You don't use 'do' because it is not a question.

'How is your Mandarin?' is fine.
