Perhaps you should try some spelling variations:
yan liang » yang liang, wang liang, you liang
heat gain » health gain, health gains, wheat grains
yang jui » yang judy, yang di, yang xi
man can » woman can, man kann
man han » man hat, man kann, man what
woran » woman, moran, goran
hai » hadi, haji, hari

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: woran ((man can) OR (man han)) heat gain ((yan liang) OR (((pang jun) OR (yang jui)))) dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "woran ((man can) or (man han)) heat gain ((yan liang) or (((pang jun) OR (yang jui)))) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: woran ((man can) or (man han)) heat gain ((yan liang) or (((pang jun) OR (yang jui)))) dang hai ;*.
