Perhaps you should try some spelling variations:
juan meng » juan rene, jui meng, yuan ming
meng tang » leung tang
tang tang » taizong tang
yang yao » yang yang, wang yan, yang fan
wong yue » hong yu
wang yue » wang hua, wang yan, wang he
yang yi » yang di, yang xi, yang jui

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: dong ((yang yao) OR (yang yi)) juan meng tang tang ((wong yue) OR (wang yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang yao) or (yang yi)) juan meng tang tang ((wong yue) OR (wang yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((yang yao) or (yang yi)) juan meng tang tang ((wong yue) OR (wang yue)) ;*.
