How to start learning Vietnamese?

Chào!
Ever since I was young I’ve been interested in Vietnam. It seems very different from all the other SE asian countries and the language also stands out a lot.
So here I am starting out to study at home before traveling there next year.
What would be a good starting point? I already speak some Chinese so the tones hopefully won’t be a big obstacle to get over. Apart from DuoLingo, which i’m currently using what other resources would you recommend me to check out?
Thanks,
Andy
