"This is a very high score for Bulgaria and means tremendous confidence in the festival and recognition from around the world," Slavova said.

As many as 11 Chinese films will be screened during the festival.

Six of them, including Go To City ELE, Keywords of Animation, The Life Of Smartphone Addicts, The Mask, A Miner's Story, and BLOOM, will compete for the festival's awards.
