Flight transfer from Tianjin Airport Terminal 1 to Terminal 2

Hi, i will arrive in Airport Terminal 1 by Air China flight from Suvarnabhumi, Thailand, at estimated time 7.10 am. Is there enough time for transfer to Terminal 2 of Airport for OKAir flight to Kunming at 9.30 am without boarding any airport shuttle bus?

Do all airport arrive in and depart from Tianjin Airport at Terminal 2?

Last time when i touched down in Airport by AirAsia X, it appears small enough to reach the Arrival Hall quickly.

I wonder Airport has changed.
