How much sons did wang long have?

He had three sons.

Wang Lung sees her as the mother of his children and the one responsible for making sure he is comfortable. She is his helpmate up until the time he becomes wealthy, at that point he looks towards other things in life...... things that money can buy. He finds her ugly because her feet were bound and he continues to see her as mother and housekeeper, but she is no longer seen as a wife, and he disrespects her by bringing women into her house and allowing even the women to act condescending.
