About arrival Kunming from Bangkok (Air Asia) at 11:40 and flight to Lijiang at 13:00

My name is Liliane.
We will arrive in KMG with Air Asia on the 14/07 at 11:40 to catch a flight to Lijiang.
When I booked on the 5th of May the the departure time with China Eastern was 13:30. I supposed it was possible to be on time.
Now I see on my tickets that the departure time has been changed to 13:00 ! Half an hour earlyer.
Is it still possible to catch this flight ?
Thank you for your answer.
