Perhaps you should try some spelling variations:
wang yidan » wang yan
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
gain yang » dan yang, daun yang, tan yang
hua gain » heat gain, run gain, hua ban
wang hui » wang zhi, wang wei, wang he
yang x » yang xi, yang _, yang 8
x wang » _ wang

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: "((((yang yang) OR (wang yang))) OR (wang yidan)) wang hua gain yang x wang hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang yang) OR (wang yang))) OR (wang yidan)) wang hua gain yang x wang hui ;*.
