In the book the father tells her that he is going to work on the trans continental railroad .But in the making of it her father passes away but she paints the train and railroad and rides it with her father
This takes place when people needed a faster way to get across continents . So many people left China and their family to work onthe trans continental rail road
my life would've changed if I lived back then because I would be very sad if my dad left me to work on a railroad. I also would not have known about how dangerous it was.
