Hi @M_tTrau ! Please pardon me for responding in English.
This post contains super useful tips and step-by-step guidance that will help you organise your meet-up - from planning to hosting. Be sure to also submit your meet-up details to our meet-up site!
It’s always good to gather Local Guides in your area first. Try searching the community for mentions of “Quảng Ninh” to find posts that have that name in the title, body of the post, or the location tag. Feel free to jump into these conversations, engage with the Local Guides near you, and plan a meet-up.
As you are new here, I recommend reading this post for best practices when using Connect.
