After watching all the episodes, I wanted to find out if they also include the Vietdub version, however, I did find, Hindu, Thai, Tamil, Tagalog and Khmer dubs. After I searched all the Vietnamese drama websites for The Untamed in Viet dub, I realised that they only do Thuyết Minh which means "Voiceover". I was so devastated that they don't even do Vietdub, like "Word of Honor", but they did nailed "Fighter of the Destiny" and "Princess Silver".
In Vietnam we called it "Lồng Tiếng" which stands for Vietdub but however, but it doesn't show up on the episodes boards, only it shows Vietsub and Thuyết Minh.

Good news for me, I have to create my own Vietdub for the characters.

I’ve been searching for almost half a month and couldn’t find any Vietnamese voice actors and actresses' information including their names. These dubbed voices a clearly unknown from the characters in different dramas but it’s does suited well The Untamed characters. However, for Wei Wuxian, I’m probably sure that I found both dramas have the same voice actor (Not sure about Lan Zhan but his voices are quite similar).
