I have to explain that this book should be considered realistic, but I don't want to write it exactly like reality, my purpose in writing this book is to give a little bit of advice to the engineers who do engineering, hoping that they can enter the leadership position as soon as possible and obtain their own value.

Therefore, in this book, the first part, there are many engineering and technical things, ordinary people may not understand, if you don't understand, you can leave a message I will explain one by one, if you encounter problems in engineering, and I understand, you can also leave a message, I must know everything.

I just hope that this book will improve my engineering technicians, and that's what I'm writing this book for. xh118
