宿黎 (Su Li) was born exactly eight days after the scarred prince of Britain the Savior of Wizarding Britain. This gave Li the auspicious birth date of the eighth day of the eighth month in year eighty.
Su Li's given name is "Li," not "Su." Many people misunderstood because Cho Chang (张秋) follows the Western convention of givenname-surname, instead of the Chinese convention of surname-givenname.
