Why do Winnie and Hulan still put up with each other?

To answer the question of why Winnie and Hulan put up with each other, a simple answer is that they are family.  There is more than one definition for family.  Family can mean that people are related by blood or all have the same ancestor.  Family can also mean people who related to each by loyalty and intimacy.  Hulan and Winnie are family by using the second definition above.  This kind of feeling of family grows over time and what the people in the family have been through together.  The two woman have spent a large portion of their lives together because of their husbands' work.  They have also been through many events together.  They have even been through war together.  Going back to the main question, Hulan and Winnie do not agree on everything but they are family.
