International student life

Hello, everyone. My name's THAO. I come from Vietnam.
Now, I'm studying in Japan.
From now I would like to tell everyone about my life in Japan.
I came to Japan 5 years ago.
It sounds long for five years but I fell like yesterday.
I am not an international student at the national expenses, but a private expense student. So my life can not afford so much economically.
I have to work part-time in order to pay for my life and tuition.
there are lots of hard work at a part-time job, but I learned a lot of things.
For example, perseverance, human relationships, and honesty.
I think it is more important than money.
Currently, I am studying ear acoustic authentication. It is said that this research theme is only in Japan worldwide.
Recently, the word block chains have heard, so I've looked up a little about the virtual currency.
Thank you very much though it is my first blog.
