Together with her husband, she runs the Nyan-Nyan Chinese restaurant. Physically, she is a tall woman with black hair typically styled in two buns.

Before settling into family life and restaurant management, Feichun had a brief career in the entertainment industry during her childhood, performing under the stage name Lee Meifa as a singer and model. She later married the chair of her booster club and redirected her focus toward running the family business. Despite leaving show business behind, she retained a strong influence over her niece Minmay, encouraging and supporting her aspirations. When Minmay moves in with her aunt and uncle on South Ataria Island to pursue her dream of becoming a star, Feichun serves as a key familial figure in her life.

Feichun's role in the story is centered on her family connections. She provides a stable, domestic presence aboard the SDF-1 Macross after the ship is caught in the conflict with the Zentradi. Her primary motivations involve caring for her family and maintaining the restaurant, which becomes a small hub of normalcy and comfort for those on the ship. Through her relationship with Minmay, she acts as a grounding influence, offering guidance and support as her niece navigates the pressures of sudden fame and the chaos of war.

Her notable ability lies in her past entertainment experience and her knack for bringing people together through food and hospitality. This background subtly informs her interactions and her understanding of Minmay's career path. Over the course of the series, Feichun remains a steady, behind-the-scenes presence, her character emphasizing themes of family, continuity, and everyday resilience in extraordinary circumstances.
