Is “Witnessed Cao Ren's charge to rescue Niu Jin” true?

The official history 'Records of the Three Kingdoms', Book of Wei, Biographies of the Various Xiahou and Cao, records that when Cao Ren charged, 'Chief Clerk Chen Jiao was also on the city wall, and seeing Jin and others about to perish, everyone's countenance changed... When Jiao and others first saw Ren go out, they were all afraid, and when they saw Ren return, they sighed and said: 'The general is truly a heavenly man!'' In 'Romance of the Three Kingdoms', Chapter 79, he is listed among the officials urging Cao Cao to accept the throne: 'Chen Jiao, Chen Qun, Huan Jie, etc.'
