Beloved Vietnam

My name is Pham ThuDzung. I'm a Vietnamese by birth. I've become disabled due to the Vietnam war. My mother taught me how to read, write and do some basic mathematics. I love my country where I lived in the early years of my life then one day unequipped with passport and luggage, the wind rushed me to the US, a strange land where I didn't understand that language....
Then, I learned English and have a job. I've missed Vietnam and love my country above all. I asked the wind to spread my story as it scatters all over the world.
Hope you enjoy Beloved Vietnam, and.... Could you figure out the purpose of the writer?
