Perhaps you should try some spelling variations:
dong qian » gong qiang, ong kian, dong sin
qian wang » yiqian wang, qian rong, qian yan
yang minh » yang mind, kang minah, anh minh
sang minh » kang minah, anh minh, song min
hui kian » hui sin
zhai fan » zhang fan
hui fan » hui yang, shui nan
cong » congo, long, hong

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 qian wang ((((hui fan) OR (hui kian))) OR (zhai fan)) ((yang minh) OR (sang minh)) cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong qian wang ((((hui fan) OR (hui kian))) or (zhai fan)) ((yang minh) or (sang minh)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: dong qian wang ((((hui fan) OR (hui kian))) or (zhai fan)) ((yang minh) or (sang minh)) cong shu ;*.
