My comprehension:ancestry应该更倾向于祖先,有历史的那种感觉
My answer:Of course it's very important for us to learn from ancestries, because they've been through a lot of things, the experiences and knowledge about the world they left could lead us to the right way. Their attitudes toward the world and those outstanding achievements they made could encourage us to pursue our dreams. Even though things are changing unexpectedly in this rapidly developing world, we still have a lot to learn from our ancestries, especially we youth.
