Answer:
In the book Joy Luck Club, Lindo Jong, one of the main characters, reflects on the idea of having "two faces" in reference to the duality of her identity as both an American and Chinese woman. She explains that in Chinese culture, it is considered polite to have "two faces" - one face that is presented to the public, and another that is kept hidden and reserved for close family and friends. This idea of having "two faces" is a recurring theme throughout the novel, as many of the characters struggle with balancing their cultural identities and navigating the expectations of their families and communities.
For example, Waverly Jong, Lindo's daughter, also struggles with her dual identity as a Chinese-American. She is ashamed of her Chinese heritage and wants to assimilate into American culture, but her mother is disappointed in her for not embracing her Chinese heritage. Similarly, Ying-ying St. Clair, another main character, feels torn between her Chinese heritage and her American lifestyle, and is haunted by the memory of her past life in China.
