Wang Lung's life is taking a turn for the worst, as his innocent children face starvation. After a successful harvest Wang Lung began to spend money in useless ways rather than saving it for his family, which is what he should have done. His uncle, a careless human being, spent money the same way. He demanded Wang Lung gave him money so he could buy food for his family. It was known to Wang Lung that the money would be on the gambling table by night, because that was the kind of person his uncle was. He should have not given his money to his selfish uncle because he knew his uncle would spend it carelessly.
After his uncle was paid there was still no rain, and starvation was spreading faster than the swine flu in our modern times. O-lan lost her newborn baby because it starved to death, so Wang Lung was forced to make a choice as any good father would have done. Packing up their things they fled to the south - a decent decision for they could either starve or try to make a change. However once they got there they had to act as beggars - something Wang Lung - or even me today, would not want to do.
