Acknowledgements
I thank my advisor, Professor Hou Yinguo, for his guidance.
I thank Fan Zhendong. When I was lost in the labyrinth of literature, your decisive shakehand sweep taught me the way to break through; when my proof models repeatedly collapsed, the flexibility of your backhand flick inspired me to grow with resilience; when the defense countdown clock flipped, your focused gaze in the deciding game gave me the power to break free from the cocoon. The trajectory of persistence you measured with your paddle is precisely the hidden signpost for my trek on the long academic road.
Under the desk lamp at 3 AM, the explosive power of your forehand smash still knocks at the barriers of my thinking; in the anxiety of countless do-overs, your increasingly brave fighting spirit on the championship journey became the most solid footnote in my thesis’s final chapter.
Those training logs soaked with sweat—aren’t they another form of academic manuscript? You turned the peak of victory and defeat into a new starting line. This philosophy of a climber who never stops taught me that the true academic journey isn’t at the final conclusion, but in every late night when I grit my teeth and continue refining.
Thank you for using the never-give-up light of sports to illuminate my long journey wrestling with words.
