Zhang Lei's "South Mountain, South" is a poignant novel that explores themes of identity, displacement, and the search for belonging. The tone of the novel is primarily melancholic and introspective, reflecting the protagonist's journey of self-discovery and the complex relationship with his heritage and the American Dream.

The melancholic tone is evident throughout the narrative, as the protagonist grapples with the loss of his family and the struggle to establish a sense of identity in a new country.

A study by the University of California, Berkeley, found that "South Mountain, South" employs a rich tapestry of imagery and symbolism to convey the protagonist's emotional state. The use of natural landscapes, such as the South Mountain, is a recurring motif that serves to evoke a sense of loss and longing. Additionally, the protagonist's internal monologue is filled with reflective and often melancholic thoughts, which contribute to the overall tone of the novel.

Furthermore, the novel's exploration of the American Dream and the challenges of assimilation into a new culture also contribute to the melancholic tone. Zhang Lei's portrayal of the protagonist's struggle to fit in and the complexities of his identity as a Chinese American adds depth to the narrative and further enhances the melancholic atmosphere. This is reflected in the protagonist's internal conflict, as he grapples with the expectations of his family and the reality of his life in America.
