How Joan Lok became Joan Chan Lok

My friend invited me to contribute an artwork to a book he was writing.  The landscape instructional book is recently published and underneath my artwork was my name misprinted as "Joan Chan Lok" instead of "Joan Lok".  Neither of us had any idea where the word "Chan" came from.  Anyway, if you see "Joan Chan Lok", it is me "Joan Lok".  For more landscape artworks by me, visit the landscape galleries in my website www.joanlok.com.  That's how I became "Joan Chan Lok."
