District Sales Manager能不能字再多点- -不少于80不就是一封邀请函？好吧，其他内容只能用编的啦。当中加一段：During the conference we will also be unveiling the latest addition to our product line, which we are very excited about.As one of our leading distributor over the years, you are the selected few who get to see these new products before they are officially introduced.
