In Terminal #2, other ppl cannot go to the check-in point In Terminal #3, the check-in point is open. all the ppl can get there. I used "Red Jacket Service" ( ppl wear a red jacket. maybe is different from 小红帽服务) to help me carry on my luggages. It is not free, but with reasonable price. I paid 10RMB for picking up my luggages and sending me out to ground transportation. There are many "Red Jacket Service" ppl, you can ask them when arriving in airport.
