I came across a reference to Cindy and was intriqued by a lady obtaining such prestigious golf positions - and also setting up a school in China. Further investigation showed that she took up golf much later in life than is the norm - at 24 years old. She considers that this means that she has had to learn from an adult prospective, rather than learning ths basics at a very early age. This struck a chord with me, as mature learners tend to look at things in a more analytical way, rather than just copying swings at a really young age.
The fact that it is written for woman didn't concern me, as I tend to think that seniors golfers are better studying lady golfers, rather than the ultra powerful men professionals.
The book itself is well written, very readable and, I guess from her own history, seemed sympathetic to the learning style of mature golf students.
I took a chance and bought a second hand copy, and am very pleased with my purchase.
Choosing one's "main instruction manual" can be a question of teaching and teacher styles. I'm sure a number of players would find this book very useful. There are some references to lady specific swing issues, but I think it is equally good reading for men golfers.
