即使是不愉快离开了单位，回信仍然这样写

不管你是什么原因离开了原来的工作单位，不要说原来单位不好，不要过分指责原来的老板，不要贬低原来的同事，即使是不愉快离开了单位，回信仍然这样写。
无忧到了新的单位就职上任，一切就绪，为了和以前单位的朋友保持联系，今天给以前单位那里的同事朋友发了个电子邮件，无忧与网上朋友分享，以便共同进步提高。
Hi, this is No Worry.
As you may know that now I am working in US Department of XXX, oversee the budget and fiscal operations and systems for xxx organization. I am very excited of this great opportunity.
Nine years of as xxx manager with xxx government, xxx government is part of my life no matter where I am. I love xxx government, who offered me an opportunity to develop my career and raise my family.
At xxx government, I was lucky that I worked together with you all. As an immigrant from Mainland China, I have no relatives here in America, a beautiful country. I take my work place as part of my family, and I treat you as my brothers, my sisters and my friends. I will miss you all.
With best regards.
No Worry
