Under what circumstances did Ah Chu and Ah Chi get separated from their parents, and how did they end up in the care of different parties (the Mo Yung Family for Ah Chu, and Ding Chun Chou for Ah Chi)? They were sisters, but not twins, so did they lose contact with their parents on the same occassion or separately? When Ah Chi found her parents again, had she been looking for them, or did she just coincidentally turn up at their place at the same time that her sister did?
