The great grandpa and grandpa ARE TWO DIFFERENT PEOPLE. The great grandpa is the one who made Yiyi's amulet and the grandfather of Jin Yao's father while JinYao's grandfather is the great grandpa's son. THE GREAT GRANDPA is a good guy while I doubt about the GRANDPA. I got a feeling like he is going to be antagonist of the story.
