Li Decai has nothing to do with Yao Kai's case. Because Yao Kai's case refers to the case of Yao Kai, former deputy mayor of Hefei, Anhui Province and former director of the Urban and Rural Construction Bureau, who was suspected of taking bribes, and Li Decai, former director and party secretary of the Anhui Provincial Civil Defense Office, did not have overlapping positions, and the review and publication of Yao Kai's case had nothing to do with Li Decai. So Li Decai has nothing to do with Yao Kai's case.
