This book is very practical! As a newly married person, although I may not be able to use the professional knowledge in the book, I can feel that it will be of great help to professionals at construction and municipal engineering construction sites. Moreover, the content of this book is well written. It follows the principles of easy to learn, easy to understand, and can be applied on the spot. It is divided into knowledge units and lectures. It is very systematic and practical. It reminded me of some architectural books I had seen before, which were of a similar style and gave people a very pragmatic feel. I think this book is also suitable to recommend to my friends who are doing related work. It will definitely be helpful to their work.
