Hey Te Changsheng

There is a kind of youth called special growth. They are the same as flowers. At the same age as flowers, they have chosen a path that seems to be full of flowers and specialties. Carrying heavy luggage, they traveled on unfamiliar roads in unfamiliar cities, exploring their own future in ignorance and confusion. The journey may be ignorant and hasty, and the road ahead is not clear and firm, but the youthful heart will always peel off the shackles of the shell, keep the kind soul, and lead us young people into colorful growth. I would like to dedicate this book to those close friends and colleagues who have accompanied me in my youth! Also dedicated to you who are also talented students or not...
