Working experience in VIietnam

Last in the end On the last day of June, I came back to Seoul, Korea. Before that came back, I had worked in Vietnam for 1 a year and 7 months. I felt privileged because it's a rare experience Ffor Korean women in their 20's.

I worked in Haiduong, a medium sized city,. It was an 1 hour away from Hanoi, the capital of Vietnam. Every moment I had there is was so precious to me and it will be my a valuable asset for the rest of my whole life.

I made many Vietnamese friends and hanged hung out with them often.

There are so many beautiful places in Vietnam such as Halong bay, Sapa, Mekong delta and so on. I also was able to enjoyed Vietnamese food such as Pho-bo, Spring rolls and so on and many more at these places. Luckily, a company I am working for has 3 factories in Vietnam. I will have quite often many chances to get go there for a business trip or to be a sojourning employee once again.

I would be appreciated if you correct my awkward and wrong sentences, even an article and preposition.
Thanks in advance.
