Perhaps you should try some spelling variations:
think zeng » think long
wang yang » wang yan, wang liang, wang yanling
zeng doug » jeng dong, zeng douglas
his last » als last, his host, its last
his land » das land, eds land, his many
doug bin » dong bin, dort bin, org bin
yang li » yang lin, yang di, yang xi

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang li ((his last) OR (his land)) think zeng doug bin ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang li ((his last) OR (his land)) think zeng doug bin ;*.
