The Chinese word "骇客" is formed by transliterating the English word "hacker", where "骇" (hài) approximates the "ha" sound and means to shock or astonish, capturing the disruptive connotation of hacking, while "客" (kè) means guest or person, functioning as a suffix to indicate an individual engaged in the activity, thus creating a term that combines phonetic resemblance with semantic relevance.
