about the ancient book

it was a few weeks back, when my family was talking about birthdays and things, my father suddenly jump up and fetch a really really old book from the shelf which i never know have that book. i only saw that book...i think once when i was in Taiwan. So we open that book... it is the "book of inheritence" or the family tree thingy. it went back to my grand mother's generation. or to be clearer, that book was bought 70 + years ago. and it includes the chang generation all the way up to the 17th generation. i am the 21th generation counting from.... chang something. the feeling is so cool you know, its like you suddenly know where you come from ? How you are here!it sjust like someone who forgot who they are suddenly knows how they come about. like....is it dare devil? nvm...
from that book, i reallise my birth day in the lunar calender is 14th sep, so if you all feel like it, can give me another present!!!haha
