Hello, my name Bui Van Chinh, I'm 57 years old, I come from Vietnam, Quang Ngai province.

I am a teacher at Ho Chi Minh city - University of Technology, my major is Mechanical Engineering.

I spent almost all my time in University to research about subject '3D Tube Bending Machine" and "Electric Pressure Washer". Finally, I also have some award and certificate at university.

I have retired since April 2015, so now I want to contribute my knowledges to Wikipedia.

I hope Wikipedia have more useful informations for all people in the world.

Nice to see and discuss with you!
