1) For the check-in luggage, passengers holding an adult fare or half fare ticket are entitled to a free baggage allowance of 40kg (88 pounds) for first class, and 30kg (66pounds) for business class, while20kg (44 pounds) for economy class. No free baggage allowance is granted to infants. If your luggage is over the limitation, you will need to pay for the excess weight, and some of the airports in China are quite strict with this.
Tip for this: If you are traveling together in group more than 1 people, you can use your allowance together, for example, if you have 35kg, your friend have only 5kg, it will be fine as long as you two check in together. This method also applies to 3, 4, 5 or even more people within one group, as long as you are checking in at the same time over the airport counter.

2) For the carry-on luggage, total weight of carry-on baggage for each passenger may not exceed 5kg (11 pounds). First class passengers may carry up to 2 pieces. All other passengers may carry on only one piece. The size may not exceed 20x40x55cm. Carry- on baggage in excess of the limit is subject to an excess baggage fee and must be carried as checked baggage.
