Movie
Description
Lan Di, also known as Longsun Zhao, commands as the lead antagonist throughout the Shenmue series, holding high rank within the Chinese criminal syndicate Chi You Men.

His father, martial artist Sunming Zhao, trained alongside Iwao Hazuki in China's Bailu Village. Entrusted with safeguarding the Dragon and Phoenix Mirrors, Sunming Zhao later died under disputed circumstances in Mengcun. Lan Di firmly believes Iwao Hazuki murdered his father. Orphaned by this event, Lan Di was raised and indoctrinated by the Chi You Men.

Physically imposing at 6'1" (185 cm) and 188 pounds (85 kg), Lan Di sports black hair in a long braid, a prominent scar on his left cheek, and a Chi You Men insignia tattoo on his wrist. He consistently wears a gold dragon-printed silk ceremonial robe or changshan over a green undergarment, projecting a cold, intimidating presence with minimal emotional display.

Driven by vengeance for his father, Lan Di confronted Iwao Hazuki in Yokosuka, Japan, during November 1986. At the Hazuki dojo, he demanded the Dragon Mirror, overpowered Iwao, threatened his son Ryo, secured the mirror's location, retrieved it, revealed his identity as Sunming Zhao's son, and delivered a fatal blow using the Tiger Swallow Style technique, killing Iwao. Lan Di then departed Japan.

His quest expanded to find the Phoenix Mirror, counterpart to the Dragon Mirror. Forged from Phantom River Stone in Bailu Village, the mirrors are believed to form a map to a treasure linked to resurrecting the Qing Dynasty or the mythical Chi You. Lan Di traveled to Hong Kong, attempting to kidnap his father's associate, Yuanda Zhu. Ryo Hazuki and Wuying Ren thwarted this, though Lan Di acknowledged Ryo's persistence before leaving.

Lan Di later surfaced in Niaowu, China, collaborating with fellow Chi You Men leader Niao Sun. Confronted by Ryo at a castle, Lan Di noted Ryo's improved skills but effortlessly defeated him. During this encounter, Niao Sun betrayed Lan Di, igniting the castle in a power grab. Offered a fake Phoenix Mirror, Lan Di released Ryo and remained unnervingly calm within the inferno, implying assured escape. He subsequently headed for the Cliff Temple, a site connected to his father's history with the mirrors.

Despite opportunities, Lan Di consistently refrained from killing Ryo, suggesting a complex internal code or recognition of their parallel vengeances. His ultimate objectives extend beyond personal revenge, potentially encompassing his father's legacy or the mirrors' mystical power, deeply influenced by his Chi You Men upbringing and allegiance.

In the anime adaptation, Lan Di inflicted the scar on Ryo's cheek during their initial confrontation, a deviation emphasizing their direct adversarial link. Non-canonical scenarios depict Lan Di killing Ryo or Shenhua Ling under specific unmet conditions, outcomes outside the core narrative.

Lan Di's background as a victim of Chi You Men manipulation, fused with his singular focus on retribution, frames his actions within tragedy and indoctrination. His role in the broader prophecy surrounding the mirrors and Shenhua Ling continues.
