"Hao" seems to the currency of Veit-nam
and "long" means dragon (in Chinese)
so I'd say the awnser is no - Hao Long is not a chinese name- after all, I wouldn't call my kid "Dollar"
But an even better awnser, thanx to wiki.
Hao (Traditional Chinese: 號; Simplified Chinese: 号; pinyin: hào; Japanese gō; Korean: ho) is an alternative courtesy name, usually referred to as the pseudonym. It was most commonly three or four characters long, and may have originally became popular due to people having the same zi. A hao was usually self-selected and it was possible to have more than one. It had no connection with the bearer's ming or zi; rather it was often a very personal, sometimes whimsical, choice perhaps embodying an allusion or containing a rare character, as might befit an educated literatus. Another possibility was to use the name of one's residence as one's hao; thus Su Shi's hao Dongpo Jushi (i.e., 'Resident of Dongpo' ('Eastern slope'😉, a residence he built while in exile). An author's hao was also often used in the title of his collected works.
In which case...."long" (Dragon) may indeed be a chinese name....
