Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
yan liang » wang liang, you liang, yan wang
dang hadi » dang hai
gan guan » yan guan, quan guan, fan guon
tan ying » fan ying, ran ying, tan yang
ying yi » yang yi, ming yi, ping yi
yi dang » yi gang, yi yang, yi chang

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: (wan OR lang) hyoung ((gan guan) OR (((yang liang) OR (yan liang)))) tan ying yi dang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: (wan or lang) hyoung ((gan guan) or (((yang liang) or (yan liang)))) tan ying yi dang hadi ;*.
