My father came to visit me in Macau during the weekend after my grandmother's birthday dinner. We somehow started a discussion about finding our root. My grandfather (father's father) passed away few years ago. He didn't kept much record of the past, neither did my father.
Creating family tree needs persistence. My father and I felt a sense of urgency for this task since we have been the eldest sons in our Lam's family for 3 generations and we have no clue about our past!
