First notebook entry: Introducing myself

I'm Ling from China. Currently I live in the south of France. In fact I studied in the University of France then I found a job here. I was an assistant to the sales director in a photovoltaic company which is in charge of installing solar panels on the roofs of buildings. I have been in this firm more than two years and I have gained much experiences and knowledge. But now I want to change the direction of my career. I’m willing looking for a job in the field of international trade  so that I can take my advantage of Chinese language and of inter-culture in the same time I can avoid my small defect, such as not speaking French like a really native French speaker; and this is a job I really want to do. So I quit my job and I met my difficulty quickly. As English is the most important language of whole world, I need to speak well too with another countries‘s clients or coworkers or someone who can’t understand Chinese or French. I had an interview two weeks ago, since I didn’t practice English in a long time and I was so nervous during my interview, unfortunately I didn’t get this position. That why I’m here now, I want to improve my English and if I can help some people like me (having trouble in language) that would be my pleasure.
I would like to take this opportunity to express my thanks for everyone who help / will help me.
Thank you guys; you are such kind women and men.
