Perhaps you should try some spelling variations:
yan hyoung » man houng, min hyoung
hyoung sau » young sae
wang yong » wang yang, wang yan, wang shiyong
zhang yan » zhang fan, zhang jian, wang yan
phang li » zhang lin, tang li, heng li
zhang li » zhang lei, zhang lin, zhang i
wu zhang » wu zhong, _ zhang, li zhang

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 yong) OR (wang hyoung)) ((phang li) OR (zhang li)) wu zhang yan hyoung sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (wang hyoung)) ((phang li) OR (zhang li)) wu zhang yan hyoung sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (wang hyoung)) ((phang li) OR (zhang li)) wu zhang yan hyoung sau ;*.
