It'll be offensive and unsuccessful. For a Chinese, you'll get the response when you break into a White House meeting and fly a Confederacy flag. For other students attending the event, it shows your unawareness of current international practices.
There're only a dozen small countries in the world that do reconginze Taiwan as a country.
Take heart that NONE of the students at the event will be from a country that recognizes Taiwan as a nation. For a country to establish diplomatic relationship with China, the 1st rule is to break all official contacts with Taiwan and negate Taiwan as a nation.
Regardless of what you may hear in your neighourhood, U.S. Canada, Britain, France, Germany, Italy, you name it... all of these powers negate Taiwan as a nation and have diplomatic relationship with China though Chinese people are sick of, if not angry, with their hipocracy of making their people think the other way.
Also, those student from Taiwan are representing Taiwan as a province. Otherwise, they can't come to mainland China.
Since it's an international event, you should be aware that your actions represents that of your nation. So if you think Taiwan is a nation and raise their flag, it'll only disqualify you for being ignorant about current international practices or it can mean that you can decide for your country that it no longer wants a diplomatic relationship with China, which, makes your visa invalid. So I guess, either you'd get thrown out, which is not very likely to happen as Chinese usually try to be friendly to foreigners, or the flag gets it, which probably will happen. If you have to insist, maybe try the Chinese Taipei flag, which is valid in international events.
