Zhao Donghai is the principal of Linhai City No.1 High School and Zhao Ming's paternal uncle. He orchestrates the grade swap between Ye Feng and Zhao Ming, and when Ye Feng threatens to report to the Education Bureau, he frames Ye Feng with false accusations of stealing achievements and causing trouble, leading to Ye Feng's expulsion. He is a Martial General expert who dismisses Ye Feng as a powerless country bumpkin. His actions are driven by favoritism and the desire to secure a recommendation spot for his nephew.
