Preface In an era, there is a period of youth, whether it is leisurely and quiet, or the stars are twinkling. For us, youth is a computer, a keyboard, and a mouse. Our every day, just like computer programming, always starts from the illusory zero, opens the sky with one stroke, alternates between yin and yang, and reaches the endless world. Once upon a time, we were walking at a loss, admiring flowers in a hurry, thinking about those times when mist and rain were lingering, and the sun was shining. Even if the flowers were beautiful, the flowers were still blooming and we had little experience. Now, years have passed, but the memories of youth still linger in my heart. Looking back on the past, I feel a lot. Whenever I have free time, I think in my heart that if we are lucky enough, we will eventually embark on the most beautiful journey of life. But, it's too hasty! In the blink of an eye, youth has crossed the river, life is a reverse journey, and the past is gone like smoke. What we think about, what we remember, youth belongs to us, and more importantly, to that era. We experience it and we will never forget it. I would like to dedicate this book to the wonderful college years and commemorate the youth that will never come back!
