Private ceremony information on website

Maybe rewording it??

Family Tea Ceremony.
Parents Tea Ceremony.
This is new to me, but I hope it might help! Sounds lovely! 😊

I think things that are listed on your website should be for all your guests. If you don't intend on inviting everyone then don't publicize this event. If it's just family only then it should be easy enough to share the details with the appropriate people.

Who is your website with? I did mine on Minted, and there is an option to have private RSVPs for certain events. So you add all the events to the website, but then you checkmark each guests' name with what they are able to RSVP and see the details to. I did our Welcome dinner that way.

And if you're going to do paper invitations, you can always include a smaller card with the tea ceremony info and just include for those guests.

I'll be having a tea ceremony (Vietnamese) as well so I think it's fine for you to put your tea ceremony information on the website. My FSIL did that and only close family members and extremely close friends showed up.

The unspoken rule, at least in all the social circles that I know, is that you don't go to a tea ceremony unless you're specifically invited, and it's usually by word-of-mouth. Either the bride or the groom will invite you, or your grandma will be telling you to show up for your cousin's tea ceremony, etc... Since the tea ceremony is usually done at home, most people will know space's unlimited and they usually don't show up.

However, you know your guests best so if you want to be safe, I think PP's suggestion to title it as "Family Tea Ceremony" sounds great.

The Knot websites also have the option to add extra events and only invite certain guests! I agree I wouldn't publicize it, if you have guests unfamiliar with the culture I could see them getting confused and offended thinking they weren't invited to the wedding ceremony at all.
