Bean Curd,
I read the book was made by the Lam Sai Wing Alumni Association.
Although Lam Cho was the president, I think he didn't write it all by himself.
I think it's funny that there are people now that say they didn't help with the book, they didn't write their bio, because they had a difference with Lam Cho.
From some people I can find several pictures (also personal pictures), pictures of students, names of students, a biography (where does the personal info come from?) and even an advertisements for their schools.
