Lan Di is the main antagonist of the Shenmue franchise and one of the primary leaders of the Chi You Men, a Chinese Cartel and he is also a chinese dictatorship. He is voiced by Takahiro Sakurai in Japanese and Paul Lucas in English.
Lan Di was first seen in the opening scene of Shenmue. The protagonist, Ryo Hazuki, finds him in confrontation with his father, Iwao Hazuki. While Ryo is subdued by his henchman, Lan Di demands the Dragon Mirror from Iwao to which he refuses and the two engage in battle. Lan Di knocks Iwao to the ground which prompts Ryo to attempt an attack. He is overcome with a single blow by Lan Di who uses him to force Iwao to reveal the location of the mirror. As he is about to finish off Ryo, Iwao submits and confesses the location. As his henchman leave to get the mirror, Lan Di asks if Iwao remembers Sunming Zhao who Iwao apparently murdered in China long ago. From this Iwao finally recognised Lan Di and the two once again fight. Iwao's attacks were easily dodged by Lan Di who easily defeated him with a Tiger Swallow Style blow. Lan Di prompts Iwao to get up once again so that he may "die like a warrior". Lan Di inflicts a final blow on Iwao, killing him. The henchmen return with the mirror and they leave the Hazukis.
After this, Lan Di immediately sought to leave the town in his black car and accidentally killed a cat on the way. He also got into a confrontation with Tom Johnson, the owner of the hot dog stand after almost running over one of his customers. However Lan Di quickly diffused the issue by giving Tom an intimidating stare. Lan Di remained in Japan for unspecified reasons and then left to Hong Kong via the New Yokosuka harbour.
Lan Di's activities in Hong Kong are not known but he is eventually seen in Kowloon as he arrives to the Yellow Head Building's roof to kidnap Yuanda Zhu. However Zhu is rescued by Ryo who defeats Don Niu and Lan Di escapes empty handed.
During the conversation with Yuanda Zhu, Ryo learns that Lan Di is really Longsun Zhao, the son of Sunming Zhao who Iwao Hazuki murdered. This reveals Lan Di's motivations for killing Iwao. Zhu also reveals that Lan Di is travelling to Bailu village where the two mirrors were created. Ryo follows him to the area to continue is quest.
