East Turkestan WW2: which types of aircraft were left by the Soviet Air Force?

Greetings! I am researching the aviation history of East Turkestan and understand that a number of Russian aircraft were left there by the Soviets in 1944-1945, and subsequently recovered by the Nationalist Chinese. I know the topic is very obscure, but what types of aircraft were found by the Chinese in 1945? Does anyone have photos or references, or perhaps tell us what happened to the planes? Thank you very much.
