You 100 Jin can only be checked. Most of the checked baggage can't exceed 90 kg, and the part that exceeds the free checked weight within 90 kg (the standards of different airlines are different, and so are the domestic and international ones). I can only make an analogy: from China to the United States, if the free baggage weighs less than 45 kg, it will probably cost 500 yuan RMB. You'd better call and ask the airline you want to book is more accurate. After all, there are differences between international and domestic flight regulations, and different countries are a little different. Let's see if you can check the goods and the specific cost.
