Hi everyone!

I have a question about transfer flight form international to domesctic in PEK.
I;m going to land at Terminal 3 and as well go further to Chengdu form same terminal.
As i know when i landing I have to go to the security control, fill the Arrival Card, and then use the train to go on the other side of Terminal 3 to get to the control for domestic flights?

I have only 1 hour and 30 minunts to make that change, and I'm little bit affraid if I can make it in that short time. I bought all ticets toogether so i assume that the agancy who sell it, can sell it only if the passenger can make it. Meybe is there someone who can share some information about how it looks, and if is that 1,5 hour fine?

Thans in advanced!
Sorry for not the best English
