Hello!

I am currently finishing my last two weeks in Taipei as an overseas student. Have been in Taiwan for my Chinese, approx. 4 months ... however, i am flying back to see my family in Shanghai where they currently live and have bought quite a few gifts, and others ... I weighed my luggage and it is around 24-25 kg ... I know there is a limit of 20kg .. but is it really a BIG deal, 4 kilos more ? .. :( .. i am asking because one time, during my first trip to Taiwan, I had a lot too coming back home and they allowed me to fly and not pay for 4-5 kilos more .. According to the number of passengers, my overseas program student situation, etc ... is there a chance or not? i am just stressing because of this luggage allowance .. Thank you very much! ps: and if not, how much would it cost me ?!
