Perhaps you should try some spelling variations:
kong saur » kong sar, kong siu, kong your
yang y.c » yang yao, yang yue, yang yun
yang 4.3 » lng 4.3, yang 47
hua chen » jui chen, yu chen, a chen
chen yan » chen yang, chen tan, chen yun
yan minh » tuan minh, sang minh, yang mind
wong siu » wong shiu, kong siu, wong sau
yang yi » yang di, yang xi, yang jui

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 ((((yang y.c) OR (yang yi))) OR (yang 4.3)) hua chen yan minh ((wong siu) OR (kong saur)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang y.c) OR (yang yi))) or (yang 4.3)) hua chen yan minh ((wong siu) or (kong saur)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yang y.c) OR (yang yi))) or (yang 4.3)) hua chen yan minh ((wong siu) or (kong saur)) ;*.
