What is the importance of the market in the novel, The Old Woman With the Knife?

The market is located not far from the clinic. After meeting Dr. Kang, Hornclaw starts visiting this location with increased frequency. The market is an assemblage of small shops and stands, all run by private business owners. Dr. Kang's mother and father are just two of such owners. When Hornclaw visits this setting, she also visits the Kangs. She chats with Kang's mother, and observes her interactions with her husband and granddaughter. Although the Kangs have no idea who Hornclaw is, they are kind to her. Being near the family during these market visits, augments Hornclaw's longing for a similar sense of belonging.
