Resignedly opening the door, he happened to bump into Zhang Zhongxing, who was about to knock again. His hand was raised halfway when he found the door automatically opening with Director Yang standing in front of him. Zhang Zhongxing didn't slow his motion and directly delivered the knocking action onto Director Yang's face.
"Knock, knock, knock."
Three quick knocks in succession, so fast that no one had time to react. Director Yang could only be dumbfounded, becoming an incidental door until Zhang Zhongxing pretended and called out, "Oh, Director Yang, why didn't you say you were opening the door? That must have hurt."
Director Yang forced a smile, touching his quite sore forehead. "It didn't hurt."
Zhang Zhongxing rolled his eyes and gave a fake smile, "Good thing it didn't hurt, otherwise it might have caused some mix-ups."
