No, by querying official website of Suzhou Education Bureau, we know that the music interview of Suzhou Sixian Primary School is PEP version, so it is not PEP version. "People's Education Edition" refers to the "People's Education Edition", and the so-called "Edition" refers to the textbook edition, not the "Edition" of the publishing house. So "People's Education Edition" refers to the textbook version published by People's Education Publishing House.
