Perhaps you should try some spelling variations:
huang ying » huang jing, huang ting, huang yang
wang yang » wang yan, wang liang, wang yanling
gain john » grin john, gutin john, swain john
bonn ein » bonn mein, bonn die, bonn iii
kann ein » kann eine, kann die, kann man
china n » china 1, china 2, china 6
china 3 » china 1

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: ((wang yang) OR (huang ying)) can ((china n) OR (china 3)) gain john ((bonn ein) OR (kann ein)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (huang ying)) can ((china n) OR (china 3)) gain john ((bonn ein) or (kann ein)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (huang ying)) can ((china n) OR (china 3)) gain john ((bonn ein) or (kann ein)) ;*.
