Perhaps you should try some spelling variations:
keong shu » cong shu, jeong su
kin keong » king kong, min jeong
yang 4.3 » lng 4.3, yang 47, yang y.c
yang hui » yang jui, wang hui, yang muxi
tong kan » tong king, gong kai, ong ka
yang yi » yang di, yang xi, yang jui
kan kin » kan min, kang kim, pang kin
ya hui » ya hua, yi hui, yuan hui

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: ((yang 4.3) OR (yang yi))ng ((ya hui) OR (yang hui)) tong kan kin keong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang 4.3) or (yang yi))ng ((ya hui) OR (yang hui)) tong kan kin keong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang 4.3) or (yang yi))ng ((ya hui) OR (yang hui)) tong kan kin keong shu ;*.
