Well, maybe you guys don't really understand my opinion. My opinion is: China didn't produce any MG 34, but some were used by Chinese army before 1949.
Although some Chinese sources state that PLA asked Soviet Union for some captured German weapons in 1946, but I don't think PLA got any during the Civil War. There are some late-WWII German weapons in Chinese museums, and I believe the saying that they were purchased from Soviet in 1950s for training purpose.
Maybe these MG34s showing in document photos and being used by PLA are from Europe or North Africa(KMT bought some weapons from Europe after WWII, like the M-10 tank destroyers, etc), I don't know.
