min keong » kin keong, min keying, min hong
min jeong » kin keong, min hong, mun leong
yan yang » yao yang, dan yang, tan yang
li song » li cong, li rong, kim song
di li » li li

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yang) OR (((yang yang) OR (wang yang)))) di li song ((min keong) OR (min jeong)) shu ;*.
