Perhaps you should try some spelling variations:
tuan china » wuhan china, can china, taiwan china
tan chia » than china, can china, dan china
wen yong » wang yong, chen yong, zhen yong
yong jin » yang jin, ying jin, song jin
jin kang » jin chang, jin kyung, jing fang
kang hai » dang hai, kang han, shang hai
wang » wing, wan

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 OR lang) yanling ((tan chia) OR (tuan china)) wen yong jin kang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yanling ((tan chia) OR (tuan china)) wen yong jin kang hai ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yanling ((tan chia) OR (tuan china)) wen yong jin kang hai ;*.
