My ancestors on my father's side actually had written a book on our family history. And the book gets passed to the oldest son which is my uncle to add on it. My father's eldest brother even wrote a poem about our history and hangs it on the wall of his living room. Thank god he has a son. I am not interested in any history and don't count on me to write with a brush... They want me to read that book but I would rather watch "Gilmore Girls."
I don't hate my background (acually I'm thankful for it). I just think watching television or surfing on the internet is more interesting than reading the history of my dad, and uncles, and their relatives... I've known these people for over 31 years and I can guess that thing is boring. If only it was as exciting as "Silence of the Lamb," I would finish it overnight.
Keeping a book of one's family history is definitely NOT a common practise in today's Chinese society. My family do it because some relatives say we had a famous ancestor who I've never heard of ... But I know some villages in Hong Kong do keep the records of every male habitant who bears the same last name of a particular village (e.g. the village of Ho).
They do it because HK is very crowded, and the government often needs to buy land (within top five of the most expensive in the world) for development from these country bunkins. The main purpose of these villages' records is to make sure the proceeds from land sales are ditributed to the real locals (males whose ancestors were also habitants of the same village).
