Perhaps you should try some spelling variations:
hyoung zhang » kyoung yang, young change
liu yong » liu yang, liu yirong, jim yong
yong shu » cong shu, tong shui, wong shiu
wei sin » wei hsin, hei sing, wei ming
wei bin » wer bin, wei ben, wei hsin
yan liu » yan jiu, yang lin
wang » wan, lang

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: (wang OR wing) hyoung zhang ((wei sin) OR (wei bin)) yan liu yong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wing) hyoung zhang ((wei sin) or (wei bin)) yan liu yong shu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wing) hyoung zhang ((wei sin) or (wei bin)) yan liu yong shu ;*.
