Vietnamese is easy to speak

I am a doctor and Ph.D. student in Taiwan currently. I had a Vietnamese teaching experience many years ago when I was a student. My English is also fluently, so you have never mind that we will have misunderstood in my class.
That is my pleasure to spread the culture and language to more people who love Vietnam. Moreover, online or offline are both convenient for me. That will not be a barrier for us to absorb new knowledge.
Don't be hesitate to contact me if you want to improve your language skill.
