hua rene » hua ren, juan rene
yang jie » yang jin, yang di, yang jui
hong shu » cong shu, tong shui, wong shiu
yaa hua » ya hua
yan jiu » yang jin, pang jiu
jing ji » ying jin

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 nana yaa hua rene ((((yan jiu) OR (yang jie))) OR (jing ji)) hong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong nana yaa hua rene ((((yan jiu) OR (yang jie))) or (jing ji)) hong shu ;".
• Adding a wildcard symbol may retrieve word variants: dong nana yaa hua rene ((((yan jiu) OR (yang jie))) or (jing ji)) hong shu ;*.
