Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan
yang liang » wang liang, yan liang, yang yang
iii gender » ii gender, i gender, iii gene
liang yan » liang dan, liang ying, wang yan
liang tan » liang dan, liang sun, wing tan
cong zhi » zhong zhi, wang zhi, cong shu

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 guang) OR (yang liang)) iii gender ((liang yan) OR (liang tan)) cong zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang guang) or (yang liang)) iii gender ((liang yan) OR (liang tan)) cong zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang guang) or (yang liang)) iii gender ((liang yan) OR (liang tan)) cong zhi ;*.
