Sunming Zhao (Hànzì: 趙孫明, Pinyin: Zhào Sūnmíng, On'yomi: Chō Sonmei) was Lan Di's father.
Yuanda Zhu says that Iwao murdered Zhao accidentally in Mengcun, and that is the reason Lan Di went to kill him. Although, Zhu believes that it happened, and it could not be true.
Zhao's death left his only son, Longsun (Lan Di), to be raised by the Chi You Men.
- There was a theory that the unknown man in the Photo of Father is Sunming Zhao. This was confirmed in Shenmue III.
