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, kann ein
china n » china 1, china 6, china 4
china 2 » china 1, 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 2))) OR (china 3)) gain john bonn ein ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (huang ying)) can ((((china n) OR (china 2))) or (china 3)) gain john bonn ein ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (huang ying)) can ((((china n) OR (china 2))) or (china 3)) gain john bonn ein ;*.
