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 lin » zhang xin, zhang jin, zhang li
zhong yan » zhang yan, zhong yong, chong wan
phang li » zhang li, tang li, heng li
wu zhong » yu zhong, hua zhong, 2 zhong

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 lin)) wu zhong 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 lin)) wu zhong yan hyoung sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (wang hyoung)) ((phang li) OR (zhang lin)) wu zhong yan hyoung sau ;*.
