Perhaps you should try some spelling variations:
main chang » main changes, main chance, main charge
chang min » zhang ming, chang mae, chan ming
yan guan » gan guan, yan yuan, yang guang
hua main » haul main, a main, hua ban
kong siu » kong eiu, wong siu, dong sin
long des » longum des, long days, long did
yan tan » tan tan, yan clan, yan wang

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 tan) OR (yan guan)) hua main chang min ((kong siu) OR (long des)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan tan) OR (yan guan)) hua main chang min ((kong siu) or (long des)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yan tan) OR (yan guan)) hua main chang min ((kong siu) or (long des)) ;*.
