Perhaps you should try some spelling variations:
kyoung liang » kyoung yang, you liang, yang liang
wang kyoung » wang hyoung, hwang byoung, wang yong
best data » test data, cost data, best damn
liang li » ling li, qiang li, liang wei
liu wong » liu feng, liu yang, kie wong
liu yong » liu yang, liu yirong, jim yong

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 kyoung liang li ((best data) OR (best way)) ((liu wong) OR (liu yong)) sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang kyoung liang li ((best data) or (best way)) ((liu wong) OR (liu yong)) sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang kyoung liang li ((best data) or (best way)) ((liu wong) OR (liu yong)) sam ;*.
