Perhaps you should try some spelling variations:
yuan chang » yuan cheng, huang chang, han chang
fung chung » fung hung, kung chung, tung chung
yuan kang » yuan wang, chan kang, yuan kai
khan sher » han shen, khan syed, than she
chan fung » chan fong, can fund, chan eng
chung zhi » chung chi, chen zhi, chung h

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 ((yuan kang) OR (yuan chang)) ((khan sher) OR (shah syed)) chan fung chung zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yuan kang) OR (yuan chang)) ((khan sher) or (shah syed)) chan fung chung zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yuan kang) OR (yuan chang)) ((khan sher) or (shah syed)) chan fung chung zhi ;*.
