In The Good Earth by Pearl S. Buck, the farmer Wang Lung and his family go through a time of famine. In that time, girls were not very valued, and he could have sold his as a slave or even just abandoned her because of the financial burden. In fact, people urged him to.
He also didn't really seem to get love. He liked his wife for being strong and frugal but didn't like that she wasn't pretty and had a mistress, he was proud of his sons for being literate but allowed them to be so for his own pride.
Why did Wang Lung keep his daughter during the famine?
