Perhaps you should try some spelling variations:
zheng xuan » cheng guan, zheng alan
zheng quan » zheng alan
yan liang » yang liang, wang liang, yan wang
you liang » you xian, you liangzhi
die yang » die lange, du yang, liu yang
yang yu » yang yue, yang yun, yang yi
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yan liang) or (you liang)) wie die yang yu ((zheng xuan) OR (zheng quan)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan liang) OR (you liang)) wie die yang yu ((zheng xuan) OR (zheng quan)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan liang) or (you liang)) wie die yang yu ((zheng xuan) OR (zheng quan)) ;*".
