Perhaps you should try some spelling variations:
gong gang » hong gang, gong qiang, gongs gong
keong shu » cong shu, jeong su
yan yang » yang yang, yao yang, dan yang
gong min » song min, gong meng, song ming
jong min » song min, song ming, cog min
yang de » yang di, rang de, yang d
de l » de la, dr l
wang » wan

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: ((wang OR wing) OR lang) yan yang de l ((gong gang) OR (((gong min) OR (jong min)))) keong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wing) or lang) yan yang de l ((gong gang) or (((gong min) OR (jong min)))) keong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wing) or lang) yan yang de l ((gong gang) or (((gong min) OR (jong min)))) keong shu ;*.
