Perhaps you should try some spelling variations:
hua brain » human brain, a brain, hua ban
yong tan » hong tan, ybhg tan, yong ben
wing tan » wing ian, liang tan, hong tan
yang jin » yang jie, yang jun, shang jin
ying jin » jing ji, yang jie
kong shu » cong shu, tong shui, kong sar
kong siu » kong eiu, wong siu, dong sin

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 ((yong tan) OR (wing tan)) hua brain ((yang jin) OR (ying jin)) ((kong shu) OR (kong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong tan) or (wing tan)) hua brain ((yang jin) OR (ying jin)) ((kong shu) or (kong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong tan) or (wing tan)) hua brain ((yang jin) OR (ying jin)) ((kong shu) or (kong siu)) ;*.
