Perhaps you should try some spelling variations:
quan guan » gan guan, quan guo, yan guan
guan rene » juan rene, glas rene
lang yan » wang yan, wang yang, zhang yan
yan quan » yan guan, yan yuan, yan clan
yang jie » yang jin, yang jui, yang xi
kong siu » kong eiu, wong siu, dong sin
yang yi » yang xi, yang jui

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