I 've been working here since September 2014. Today is August 28, 2018. Time flies, four years will pass immediately. When I look back to what I have done these years, it looked like everything happened yesterday. It was very clear. I can remember the scene that I first reached our company. My younger sister,brother-in-law and my husband went with me. At that time,this company was still under construction. The building was surrounded by a gate and the road was mud road. We needed to wear hard hat to enter the lab.And we did a lot of paperwork in the dormitory, because our offices were not ready. Four years pass, it changes a lot. Our company becomes more and more beautiful. Many excellent people work here. Now, I will leave here immediately. There are three days left.I will go to the other palce to follow my dream. I will get the new experience. I will face the new hardships. I must to become much stronger. In fact, I know I wil not happy when I really leave here. After all, I have worked here for four years. I see the changes of you from 2014 to 2018. I wish you can get a great developement in the follow years. I wish that we all will get a great progress in the future. I really appreciate to my boss. He teaches me a lot. He is an excellent man. Thank you!At the same time,thank you all of you,my workmates. As a word saying, changing is painful, but not to change is more painful. I am ready to change. How about you?
