Lan Fei Hong, known as Fei, stands as a significant rival to the protagonist Liu Mao Xing. He presents a calm and composed demeanor, marked by long light brown hair typically tied with a dark blue headband and dark blue clothing featuring orange accents.

Fei first emerges during the Super Chef Examination, showcasing exceptional culinary skill to pass alongside Liu Mao Xing, establishing their competitive yet respectful dynamic. Departing on his own journey afterward, he becomes involved with the Underground Cooking Society, an organization seeking domination over China through culinary manipulation. This association ultimately positions him as a major antagonist.

Significantly influenced and brainwashed by the Society, Fei transforms into a formidable adversary, culminating as the final opponent in the original anime. In the climactic confrontation within the Forbidden City, he prepares the extravagant and elaborate "Neo-Manhan Banquet" for the Emperor of China, designed solely to impress.

His culinary philosophy shifts under the Society's sway, prioritizing grandeur and opulence during the banquet. This starkly contrasts Liu Mao Xing's focus on health and balance to improve the emperor's well-being, highlighting their central conflict.

Tofu serves as a recurring motif and key ingredient in their confrontations. Their rivalry ignites in an initial cooking battle centered on tofu, and a decisive rematch later also features tofu as the primary component, symbolizing the full circle of their competition.

Fei's character arc spans rivalry, antagonism, and eventual redemption, reflecting the series' narrative themes and underscoring the high stakes within its culinary world.
