yan yuan » nan yan, yan clan, yan kun
yan guan » gan guan, yang guang, yihan guan
zi cheng » xi cheng, _ cheng, yi chen
zhang i » zhang ii, zhang li, zhang si

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: lang ((((yan yuan) OR (fang yuan))) OR (yan guan)) zi cheng zhang i song shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((((yan yuan) OR (fang yuan))) or (yan guan)) zi cheng zhang i song shin ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((((yan yuan) OR (fang yuan))) or (yan guan)) zi cheng zhang i song shin ;*.
