In "The Joy Luck Club," Amy Tan explores the concept of "invisible strength," a lesson imparted by a mother to her child at a young age. This idea emphasizes the importance of quiet resilience and strategic thinking in achieving success in life, whether in debates or other challenges. The mother instills in her child a sense of respect for others while also developing essential skills that can be applied in various situations, including games like chess.

The analogy of wind illustrates that the most powerful forces often go unseen, suggesting that true strength lies not in overt displays but in subtlety and poise. The notion that one can navigate life's complexities by harnessing this elusive strength resonates throughout the narrative, highlighting the significance of inner fortitude and wisdom passed down through generations.
