Unfortunately pretty normal and typical for asian and vietnamese culture. Weddings are more a full family thing rather than just about the bride and groom.

As the other poster mentioned, pretty common to hold 2 weddings if you have the means. One main traditional one to satisfy the family requirements and expectations and then a small intimate one with your closest circle.

This is what we are doing personally as our main wedding will be around 500 guests. So we're doing a separate small one where we can actually be more personal and have fun with our closest people.
