- "Get up, I'll allow you to die like a warrior!"
- ―Lan Di before delivering the death blow to Iwao
Longsun Zhao (Hànzì: 趙龍孫, Pinyin: Zhào Lóngsūn, On'yomi: Chō Ryūson), most commonly known by the name Lan Di (Hànzì: 蓝帝, Pinyin: Lándì, On'yomi: Rantei), is a high ranking member of a Chinese cartel known as the Chi You Men, and the lead antagonist in the Shenmue series. He is one of the leaders of the Chi You Men.
Lan Di is Chinese. He can be considered on the tall side at 185 cm (about 6'1"). His dark hair is worn into a long ponytail. He bears a vicious looking scar on his left cheek. He has a tattoo on his wrist of the insignia of the Chi You Men. His countenance is serious, strict, humorless and lacking in empathy.
Lan Di is constantly seen wearing a green, Chinese ceremonial robe with a dragon print.
Lan Di is a known figure among the four leading rank members of the Chi You Men, alongside Niao Sun (Yan Di), Hao Di (White Tiger) and Xuan Di (Black Tortoise). Based in China, they tend to shy away from appearing in public, as to not draw attention to themselves.
Although their true intentions are unknown, the Chi You Men are searching for the Phoenix Mirror which Ryo Hazuki has in his possession. This mirror is said to, when combined with the Dragon Mirror, create a map, which should lead to secrets unknown.
Despite being a secretive organization to the general public, their presence is known in the right circles. Both the Yellow Heads and the Mad Angels knew of and were working for Lan Di. Yuanda Zhu had hidden himself from the Chi You Men as he had become a target of them.
Lan Di was in search of a mysterious stone mirror known as the Dragon Mirror. His search led him to the home of Iwao Hazuki, whom he had some connection with in the past. Iwao's son, Ryo, had just returned home, and arrived at the dojo in time to see the two older men arguing. Iwao refused to divulge the information of the mirror's whereabouts, and the two martial artists engaged in a short fight. Lan Di ultimately won, and knocked Iwao to the ground. Angered, Ryo charged at the man but was easily beaten in a single blow. Lan Di approached Ryo, picking him up and holding him in the air by his neck. Lan Di then told Iwao to give him the location of the mirror, or his son would die. Just as Lan Di was about to deliver a fatal blow to Ryo's side, Iwao relented, revealing to Lan Di that the mirror was buried beneath the cherry tree in the Hazuki garden. Lan Di's henchmen walked outside to retrieve the mirror, leaving the others alone. Lan Di then asked Iwao if he remembered a "Sunming Zhao", which he revealed to be the name of a man Iwao had supposedly murdered in a rural Chinese village called Mengcun. Iwao expressed fear and surprise as he suddenly recognized Lan Di, and the two engaged in combat.
Lan Di dodged Iwao's attacks easily, and mortally wounded him with a deadly blow of the Tiger Swallow Style, a move described in a mysterious scroll Ryo later finds in the dojo. Lan Di allowed Iwao to stand so that he could die like a warrior. Iwao got to his feet, and Ryo was forced to watch as his father was mortally wounded with a savage blow. The suits then returned, having retrieved the mirror, and Lan Di left Ryo alone with his dying father.
After the murder of Iwao Hazuki, Lan Di left the town quickly, driving away in a black, luxurious-looking car, killing a neighborhood cat on his way out. The driver of the car also got into a heated argument with Tom Johnson, the American hotdog stand owner and a friend of Ryo's. It was from him that Ryo was able to learn about Lan Di's existence, as Tom had gotten a brief glimpse at Lan Di's withering stare.
Lan Di remained in Japan for a short time afterward, presumably seeking more information regarding his own quest. He then headed to New Yokosuka Harbor before moving on to Hong Kong.
Lan Di's whereabouts for the duration of Ryo Hazuki's stay in Hong Kong is relatively unknown, though is seen briefly in Kowloon, arriving via a helicopter to the roof of the Yellow Head Building to pick up Yuanda Zhu who Dou Niu had captured for him. Before he can leave with his prisoner, however, Zhu is saved by Ryo and Wuying Ren, and he leaves empty handed. As he heads towards Guilin, he seems to acknowledge Ryo, perhaps impressed with the young man's persistence and undeniable skill.
It is revealed by Yuanda Zhu that Lan Di's real name is Longsun Zhao, and that he is the son of Sunming Zhao, the man that Iwao Hazuki killed in Mengcun. Lan Di believes that Iwao was the man who murdered his father, and this was his reason for killing him. Zhu also reveals that Lan Di has left for Bailu Village, a small hamlet deep in the mountains of Guilin, where the two mirrors were created out of Phantom River Stone. Ryo again vows to follow Lan Di and travels to Guilin to continue his quest.
Ryo finally tracks Lan Di at the top of Niaowu's old castle. Lan Di has been working alongside Niao Sun, although Niao tries to betray him and kill him via burning, with intents of ruling the Chi You Men by herself.
Lan Di is seen sitting on a sofa in a room with three men whom Ryo and Ren defeat. Lan Di comments that Ryo's abilities have improved. Ryo challenges Lan Di, but Lan Di is not even phased by Ryo's attacks. As the fire engulfs the building, Ryo finds himself grappled by Lan Di who comments he has a death wish and will be reunited with his father. Ren distracts Lan Di by throwing a fake Phoenix Mirror out a window. Lan Di is last seen in the burning building, although his calmness implies he will not die.
Yunshen Yuan reaffirms Ryo's knowledge that Lan Di is the son of Sunming Zhao, an acquaintance of Ryo's father who was entrusted with the mirrors. Yuan reveals Lan Di was raised by the Chi You Men, and that Lan Di is probably at a cliff temple that Sunming visited.
- Iwao Hazuki: Lan Di killed Iwao on November 29th, 1986 and stole the dragon mirror. According to Yuanda Zhu, Lan Di murdered Iwao because he killed his father Sunming Zhao and it was a act of revenge.
- Ryo Hazuki (Non-canon): If Ryo stays in Yokosuka until April 15th, 1987 a bad ending will occur. Lan Di demands the phoenix mirror; Ryo refuses so he kills him using the same move he used to kill his father. In Shenmue III, Ryo can also be killed in the Bad Ending.
- Shenhua Ling (possible, non-canon): If Ryo doesn't do the main quest in Shenmue II, Lan Di is seen approaching Shenhua, ominously saying he will take her power.
- Lan Di's zodiac sign is Leo and he has a A blood type.
- The Shenmue team initially called and often referred him as Cang Long (蒼龍, On'yomi: Sōryū, lit. "Black Dragon") but then changed his name to make it more unique.
- In the beginning of development, Lan Di had a lion-like hair style, but then they tied his hair up because of the large amount of polygons involved and the subsequent difficulty with controlling his hair movement.
- Niao Sun and Lan Di may be hiding in a Shenmue III trailer.
- Yu Suzuki said in an interview that by the end of the Shenmue saga, Ryo does eventually overcome and lets go of his desire to get revenge on Lan Di. However, this does not necessarily mean Lan Di never dies, as there is a possibility of Lan Di accidentally dying somehow. Another possibility is that Lan Di winds up in a situation where he takes his own life, or Lan Di is killed by someone else (such as Ziming Hong).
