Welcome back! All efforts will be paid off.

I only help with a few corrections in spelling and tenses. The tenses in your second paragraph is pretty confusing. It is better to get revised for consistency in tense. But I'm sorry I'm not able to figure out it:( so I simply guess what was intended there. This is the first time I tried to correct the counterpart's text (the work related items you have grasped must be far larger than mine) There must be quite a few flaws in my corrections! Hope you don't mind.

Working in Ethiopie  [Ethiopie is maybe French? in English, Ethiopia]

Hi everyone, long time no see! It's been one year since I wrote on italki last time.

After staying at the headquarters in Beijing for one and half a years, I've since evacuated from Libya when after the turbulence ["turmoil" might be a better word to use here!] that took place at the beginning of 2012. I am working in Africa again now, but in Ethiopia this time.

Compared to the first time I worked at overseas, I spent much less time to get getting used to the life and work here. We are constructing a railway here which is our company's first project in Ethiopia. Due to the importance important role the project plays in our company's current expanding strategy, the management keeps a keen eye on the on-going progress of the project and makes it the No. number one Project of 2012. [For some reason we never shorten "number one" to "no. one", even though "no." is indeed a common abbreviation for "number."] Working on this project offers me a good chance for the self-developent in my career, however, challenges co-exists exist at the same time.

The whole railway are is divided into two parts, one in Ethiopia, and one in Djibouti where French are is the most used language besides the local ones. I started to learn French by myself one month ago. The French grammar is much more difficult than English, however, I believe every effort will be paid off for those who never give up.

That sounds like a great experience for you, good luck!
