Lan Di (藍帝) is the man whom Ryo seeks to find and the main antagonist of the series. It is known that Lan Di is a high ranking member of the Chi You Men, a Chinese black market organization that controls a lot of illegal trading in China. He is also a very skilled master of Tiger Swallow Style (虎燕拳), a deadly form of Kung-Fu.
 Shenmue I
At the start of the game, Lan Di travels with two other Chi You Men members to Yokosuka, Japan and heads to the Hazuki Dojo in Yamanose. There Lan Di confronts Iwao Hazuki and demands a Dragon Mirror from him which Iwao refuses to hand over. In order to persuade Iwao, Lan Di threatened to kill Ryo, forcing Iwao to reveal that the mirror is buried outside under the cherry tree in the garden infront of the Dojo. After taking the Dragon Mirror Lan Di asks Iwao if he remembers a man named Zhao Suming, after which Iwao seems to recognise Lan Di. He kills Iwao using his deadly form of martial arts and leaves with the mirror. Lan Di remains in Japan for a little while, before leaving for Hong Kong.
 Shenmue II
Lan Di is seen briefly in Kowloon after arriving via a helicopter to the roof of the Yellow Head Building to pick up Yuanda Zhu whom Dou Niu has captured for him. However this doesn't go according to plan as Yuanda Zhu is saved by Ryo and Ren and he leaves empty handed, heading towards Guilin. Lan Di appears to acknowledge Ryo whilst he is fighting with Dou Niu.
Whilst Lan Di is not seen for very long in the second game, Yuanda Zhu provides some new insights to Ryo and the others after he is rescued. He explains that Lan Di's real name is Longsun Zhao (趙蒼龍) and is the son of Sunming Zhao (趙孫明) whom players will recall Lan Di mentioned at the beginning of the first game as the man that Iwao killed in Mengcun. Lan Di believes that Iwao was the man who murdered his father and this was his reason for killing him.
