If it's just a normal relationship between men and women, you don't have to give red envelopes to your parents (if you really want to give them), but if your girlfriend has grandparents at home, you usually have to give red envelopes to the elderly, depending on your financial situation. 200,300,500,600,800 will do.

If it is a proposal, it should also be addressed to parents. Similar to the previous figures.

You can also discuss it directly with your girlfriend. She must know the local customs better.
