Cao Chunyang, daughter of Cao Da Hen, stands as the primary rival to Mao Lan. She possesses a martial arts foundation in Cao Family Bajiquan, supplemented by secret training in Mao Family Juhe Fist techniques received from Gangli, a former student of Mao Hung. This covert instruction specifically targeted countering Mao Lan’s signature Fajing technique. Her father commercialized their family’s martial arts, creating the Prime Mat televised fighting competition to showcase her abilities and demonstrate their style’s superiority.

She harbors intense animosity towards her younger stepsister, Cao Ling-Shen, frequently employing her as a harsh training dummy and displaying near-lethal cruelty. Arrogant, vain, and relentlessly driven to dominate opponents, she views martial prowess as a means to assert status and validate her family’s legacy.

Her core motivation focuses on defeating Mao Lan to eliminate the Mao Family Juhe Fist as a rival. This rivalry culminates in a decisive match where Mao Lan emerges victorious. Following her defeat, Cao Chunyang acknowledges Mao Lan’s strength and expresses a desire for continued growth, indicating a subtle shift in perspective. She explicitly states her intention to seek a future rematch, suggesting an ongoing commitment to refining her skills beyond their initial confrontation. Her actions and development remain tied to martial arts progression and the complex dynamics of her family’s conflict with the Mao lineage.
