I came to Shanghai 3 weeks ago from zimbabwe(Africa), my original luggage was 20kg. it was my first time travelling by air so had no idea about luggage restictions I came for a seminar for pharmacists & will b leaving on Tuesday.My first flight back will be Shanghai-Gongzhou, then will connect with Ethiopean airlines. I bought things which i put in another bag that weighs around 23kg. Now one of my colleagues has told me something about luggage restrictions.I do not have money to pay for excess luggage, & cannot bear the fact of leaving my things the airport. I'm really scared.
