其实我也是研究了很久关于线上英语培训机构的事情了，123peiyin.com也去问了很多人的意见Dear Mr. Wang，
I need to cancel the appointment I made to see you on January 29, at 9∶00 a.m. When I made the appointment, I thought I would have all of the necessary information collected so we could discuss a change of zoning in my residential neighborhood, but gathering the information has been more difficult than I had anticipated. It will probably take three more months before I am ready to discuss this proposition. I am working with a group of concerned neighbors, and as soon as we are ready, one of us will call to set up a new appointment.
