on January 16, 1969, the first meeting of the CCP Heilongjiang Core Group was held under the chairmanship of Pan Fusheng, and since then, applications for membership of the Party in the districts, municipalities, counties, and large-scale factories, enterprises, higher education institutes and scientific research institutes have been approved one after the other.
