wing tan » wing ian, liang tan, hong tan
tan jing » tan ying, wang jing, bian jing
wai yan » wang yan, wei yang
yang yi » yang di, yang xi
ji ying » jin ying, hoi ying, hui ying

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: ((wai yan) OR (((yang jui) OR (yang yi)))) zhang wing tan jing ((ji ying) OR (li ying)) system ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wai yan) or (((yang jui) or (yang yi)))) zhang wing tan jing ((ji ying) OR (li ying)) system ;~".
• Adding a wildcard symbol may retrieve word variants: ((wai yan) or (((yang jui) or (yang yi)))) zhang wing tan jing ((ji ying) OR (li ying)) system ;*.
