quan guan » gan guan, quan guo, yan guan
chih fong » chew fong, chan fong, chih hang
fong kong » hong kong, king kong, sing kong
kong saur » kong sar, kong siu, kong your
yan yuan » yan guan, fang yuan, nan yan
tuo guan » gui guan

• Adding a wildcard symbol may retrieve word variants: lang ((((yan yuan) or (tuo guan))) or (quan guan)) li chen chih fong kong saur ;*.
