guan shi » guan li, puan sri
ran ying » tan ying, jin ying, gao ying
fan ying » fan xing, tan ying, jin ying

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang OR wan) OR lang) gan guan shi ((ran ying) OR (fan ying)) jin ((long han) OR (long chain)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wan) or lang) gan guan shi ((ran ying) OR (fan ying)) jin ((long han) or (long chain)) ;*".
