Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
yang chia » yang chik, hang china, tan chia
kong land » kong lyn
kong hang » kong heng, kong hong
chia tan » chia lan, chen tan, chia wen
long han » long chain, long thanh, long haul
hong hai » shang hai, zhong tai, dang hai

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 yang chia tan ((kong land) OR (kong hang)) ((long han) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang chia tan ((kong land) OR (kong hang)) ((long han) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang chia tan ((kong land) OR (kong hang)) ((long han) or (hong hai)) ;*.
