Where does Wang Lung decide to move his family in The Good Earth?

In The Good Earth, Wang Lung does
decide to move his family south when a drought takes over the land, but this happens
earlier in the novel.  In Chapter 29, Wang Lung and his family have already returned to
their land, and they have met prosperous harvests over the years.  Wang Lung has taken
Lotus as his second wife, and his sons are older--the eldest married and his wife is
soon expecting a child.  Wang Lung buys the House of Hwang and decides to move his
family from the farm to the courts at the big house.  The women continually fight, and
Wang Lung wants peace, so he figures that moving them to separate courts in the House
will be a good decision.
