plz advise me again
Apart from the usual documents showing your relationship is genuine, a concise, thorough and clear narrative of your relationship backed up with third-party evidence such as receipts in both your names, travel ticket stubs showing dates of visits to each other, friends/relatives affidavits demonstrating your relationship is genuine, letters/cards/invitations sent to both of you, etc.
Anything that in your view will strengthen your case. Those are only examples. You can probably come up with others, maybe brainstorming together with your spouse/partner can bring other ideas.
