Posts - What did the "tigers" do?

Twelve out of the 63 investigated officials were from organizations and departments of central committee of the Communist Party or central government. Five of them were senior military officers and three were senior executives of State-owned enterprises. The rest 43 were from 23 provinces.

CPPCC leaders at national and provincial levels were the most "dangerous posts" as two vice chairmen of CPPCC National Committee and 11 chairmen and vice chairmen of CPPCC provincial Committees were probed.

Retired officials were no longer safe anymore as six senior retied officials were also investigated; among them Zhou Yongkang and Xu Caihou.
