Ji Yunhao's hat caused a heated discussion among the netizens. Ji Yunhao was wearing an officer's hat when he was in the army, not an ordinary soldier's hat. This caused some people to doubt that Ji Yunhao's promotion from a soldier to an officer in just two years might have something to do with his outstanding performance in the army. In addition, some people speculated that Ji Yunhao's rapid promotion was related to his family background. They suspected that his father might be a high-ranking official. However, the government had already refuted the rumor. Ji Yunhao's father was not a high-ranking official, but an ordinary citizen. All in all, Ji Yunhao's hat had raised some questions and speculations, but the specifics were still unknown.
