I went to go from changha to Ethiopia Via beijing. how much lauggage kg allowed to me?

For the domestic flights, you can take 20kg checked lugagge for free if you hold the economy class ticket and for the business class air ticket, you can check in 30kg for free. The carry-on luggage should be within 5kg.

For thr international flights, I heard the weight of checked luggage is the same and the carry-on luggage should be within 7kg. You can also consult your airlines directly for the limitation.
