Perhaps you should try some spelling variations:
fang zheng » fang sheng, fang zhen, tang zheng
tang meng » tang zheng, tang min
tang tang » taizong tang
gong meng » gong gang, gong min
yuan yi » yuan li, yuan zi, yuan fei
yi yang » yin yang, yi gang, yu yang
yang xi » yang di, yang yi, yang jui
xi fang » xia fang, xi kang, cai fang

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 ((((tang meng) OR (tang tang))) OR (gong meng)) yuan yi yang xi fang zheng ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((tang meng) OR (tang tang))) or (gong meng)) yuan yi yang xi fang zheng ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((tang meng) OR (tang tang))) or (gong meng)) yuan yi yang xi fang zheng ;*.
