Perhaps you should try some spelling variations:
kang yang » yang yang, kang young, huang yang
wang yang » wang yan, wang liang, wang yanling
wing yan » wang yan, wing ian, wing tan
yan clan » das clan, yan guan, yan yuan
yan nan » yan guan, yan wang, yan yuan
nan yan » nan ya, wang yan, qian yan
hong a » hong ma, kong a, hong g
hong 7 » hong g

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: "wing yan nan yan clan ((kang yang) OR (wang yang)) ((hong a) OR (((hong 7) OR (hong w)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan nan yan clan ((kang yang) OR (wang yang)) ((hong a) OR (((hong 7) OR (hong w)))) ;*.
