离开甘肃应该翻译成leave GANSU还是Leave from gansu啊？

Now I will introduce myself briefly. My name is xxx. I am xx years old,born in Anhui Province. I graduated from UESTC. My major is constructional engineering. And I got my bachelor degree after my graduation in the year of 2001.
In July 2001,I worked in JSLC. And in March 2010,I left Gansu and worked in Hainan Spaceport of XSLS. Hainan island is a very good place with the endless sea around it ,nice beaches and bright sunshine. It has a mild climate ,beautiful flowers and sweet fruits all the year round. Welcome to hainan.
Now we are struggling on the front line of construction,exposed to all kinds of weather. Though it is very hard to work on the site,I feel very happy. I love my job,and I am very proud of settling down on hainan island and making contributions to the construction of the aerospace industry of our country.
That's all.Thanks.
再问： work on site 和 work on the site不一样吧。我是表达在现场工作很辛苦的意思。
再答： on site 解释为“到位了，可以开始工作/ 运作”，它没有“辛苦”的意思。如果你是网上得到这个短语的，我希望你放弃使用。on the (construction) site -------在工地上。 你可以说-------- though it is really a hard job that i do , i feel very happy 代替 --------Though it is very hard to work on site --------最好避免别人看不懂。语言的使用越简单越好。
再问： 嗯，谢谢。扎根海岛，怎么翻译啊？root in hainan island 不对吗？
再答： 1 settle down on the island 2 make the island one's home 3 root in hainan island ------我有一些老外朋友，但他们never这样表达。
