gong gang » hong gang, gong qiang, gongs gong
gang sung » gang und, gang gong, hung sung
tan ying » fan ying, ran ying, tan yang
chang su » chang hsun, chang fwu, chang gui
chang ly » chang ha, chang _, chang c

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: tan ying ((chang su) OR (chang ly)) li gong gang sung hui ;~.
• Adding a wildcard symbol may retrieve word variants: tan ying ((chang su) or (chang ly)) li gong gang sung hui ;*.
