Sir is used as
(1) (initial capital letter ) the distinctive title of a knight or baronet: Sir Walter Scott
(2) (initial capital letter ) a title of respect for some notable personage of ancient times: Sir Pandarus of Troy .
(3) Archaic. a title of respect used before a noun to designate profession, rank, etc.: sir priest; sir clerk.
(4) a form of polite address for a man: Don't forget your hat, sir.
(5) a salutation in a letter: Dear Sir or Madam.
So unless he was born of ancient times or as a knight or baronet, he cannot call himself “Sir 張”. He can call himself Mr. 張
I think that he is just misusing the word.
See the above definition from dictionary. #1 & #2 are title of the person born of ancient times or as a knight or baronet ancient times or as a knight or baronet. #3 to #5 are forms of polite address for a man.參考資料： Myself.
