According to the regulations, each passenger is allowed to take luggage with the total weight no more than 20kg, and external dimensions (including length, width, and height in total) should be no more than 4.3ft (1.3 meters) for free.
If your luggage is within a weight of 20-30kg, and external dimension within 4.3-5.2ft (1.3-1.6 meters), you have to pay CNY2 for it.
If your luggage is larger than 5.2ft and heavier than 30kg, they will refuse your entry.
