Perhaps you should try some spelling variations:
yuhan cheng » yuan cheng, yunnan sheng
liang wang » liang tan, liang ying, ping wang
cheng guan » cheng han, thong guan
liang dan » liang tan, king dan, liang sun
guan kong » tan kong, nan kong, yuan kang
zhang zhi » zhong zhi, wang zhi, zhang wei
hang zhi » wang zhi, liang zhi, zhong zhi

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 ((liang wang) OR (liang dan)) yuhan cheng guan kong ((hang zhi) OR (zhang zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang wang) OR (liang dan)) yuhan cheng guan kong ((hang zhi) or (zhang zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang wang) OR (liang dan)) yuhan cheng guan kong ((hang zhi) or (zhang zhi)) ;*.
