Hello Thao!
I liked your your introduction post so I just wanted to welcome you to Hive.
I've never been to Vietnam even as I've traveled many other countries. I was looking forward to it in 2020 but thanks to Covid pandemic it never materialized. Maybe when borders are open and free once again I will get to do it.

Meanwhile I hope you have a great time using this platform and HIVE crypto.
Cheers!
