My fiancé is getting tired of my cultured/traditional family

So my fiancé and I are getting married soon. I am coming from a very traditional family, we’re Vietnamese. He’s of course very freely living his own life the way he wants. He has distanced himself from his family long time ago. And he has been living the way he wants since. He also hate being told or having to follow someone else’s rules.
We did have the both family meet, and agreed on certain things about the traditional wedding.
But days go by and he started getting tired of all the traditional. First the tea ceremony, then the wedding at church. To him, we both could have just gone to city hall and register our marriage, and then have the traditional wedding later. But to me, pretty much my family, we have to get the wedding done first before moving in together. I do like his idea about having the wedding later, but I also don't want to disappoint my family.We are at the point where we have to follow so many rules, that he started disliking my familyFor example, we all first agreed to have the tea ceremony, but then I changed my mind because I thought it is not necessary to have it. but then my mom disagree on that, and she gave the condition if I don't do the tea ceremony, they wont be attending my wedding at all. and of course my fiancé got all pissed and said mean things about them to me. there are many other conflicts are too long to give it all here, but this is one of them.I don't know what to do anymore because I love him, but this is also my family. I don't know what to say or do to both sides to come to an agreement. My fiancé is mad mostly because my family is forcing us to have the wedding they want, and that they gave conditions to us to have then attend our weddings. Even though, my fiancé and I are the one who pay for the whole wedding. we dont take any help from anyone. that's why he is pissed.what should I do?
