Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
sang sing » muang sing, yang using, san using
sing kong » king kong, hong kong
yang lin » wang lin, yang li, yang liang
yang jin » yang jie, yang jun, ying jin
kong siu » kong eiu, wong siu, dong sin
xu sang » du sang, xu gang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang hyoung ((yang lin) OR (yang jin)) xu sang sing kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((yang lin) or (yang jin)) xu sang sing kong siu ;*.
