Perhaps you should try some spelling variations:
wang hong » wang yong, wang hyoung, wang lihong
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
tan chia » tuan china, than china, can china
tan yang » dan yang, tan ying, tan yong
kang hay » eang hay, kang han, dang hai
xi kang » jin kang, xi zhang

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