I'm going to arrive at Wuhan Airport T1, then i have to take an other flight from (T2) to Shenyang.

The correct transfer procedures are Flight Arrival - Inspection & Quarantine - Exit and Entry Frontier Inspection - Baggage Claim - Customs Inspection - Boarding Pass Changing - Check-in Luggage - Security check - Waiting & Boarding.

To my experience, you can complete the transfer procedures within two hours if you hurry up. But you are still suggested to consult your airline in advance. Good trip!
