I believed my son wrote something related to me in his assay or resume. This caused me remember a lot of past things. Actually, my friends, one younger mom, wanted me to share the parenting experience with her before. This year I could be able to write this story to record the growing up experience of my son from an infant to a college student through four countries. The story is subtitled according to my son's names, which changed with time as we were living in China, Singapore, Canada and the USA. They include Naonao, Dayuan, Wenyuan, William, Will and Wenyuan William Liu. So far, people still call him Will so I use this name through whole story.
