Hello windie520!

Please check my version below, to make sure that it is okay, before I replace your version with it:

My purpose in telephoning you today is to inform you of a competition we will be holding on the 12th of December, at ccmall.
This will be a huge event! We will welcome participating colleges from all over China, and there will also be an exhibit of our achievements during the two years since our foundation. On that day, we will also be inviting magazine reporters to come and report on the events. We hope all participants on the day of the competition will be of the highest caliber, and we also hope your college can send high-level competitors to participate in it as well.

What do you think?

CC: pluiepoco

winnie has spelt wrong words, like constant, which should be contest. Moreover, she had many omissions.

So her version can not be accepted, then let's check Ian's version above:

the first sentence is to say: I am telephoning you to notify that ...

journalists can be better than reporters, because it is for writting magazines.

events --> Event.

The rest is superb, I think.

Thanks pluiepoco!

Great! I'll fix it and validate it then!

Original version of translation before editing:
