The class lasted roughly an hour, during which He Hua answered some questions from the students afterward. Specifically, he walked over to Shen Xian and said, "The question you asked earlier can actually be solved in several other ways. If you'd like to hear more, we can discuss it further. Feel free to find me anytime."
After saying that, he handed Shen Xian his business card.
"Thank you, Professor He!"
Shen Xian accepted the card and stood up to thank the teacher.
Seeing that no one else had further questions, He Hua announced the end of the class and reminded everyone repeatedly to pay attention to classroom discipline, stressing that although everyone was an adult, failing to follow the rules would still affect those who genuinely wanted to learn.
As he spoke, his gaze intentionally fell on Zhao Ming, whose feet were still resting on the table.
