I went to Viet Nam in 1996. There were mostly manual labour and agricultural productions. 12 years later, when I came back, the country had dramatically changed, there were more technology and equipment and more industrial production too.
Last year, I went back to Ho Chi Minh city after 20 years and to my surprise, there were more services. There were also many opportunities for university (inside and outside the country), which were another surprise for me.
