Perhaps you should try some spelling variations:
tuan china » wuhan china, can china, taiwan china
shang hai » shang kai, dang hai, chang ha
wing tan » wing ian, liang tan, hong tan
tan chia » than china, can china, dan china
han hua » tan hua, wang hua, tuan hua
yang xi » yang di, yang jui
yang yi » yang di, 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: wing tan ((han hua) OR (((tan chia) OR (tuan china)))) gain ((yang xi) OR (yang yi)) shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing tan ((han hua) or (((tan chia) or (tuan china)))) gain ((yang xi) OR (yang yi)) shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wing tan ((han hua) or (((tan chia) or (tuan china)))) gain ((yang xi) OR (yang yi)) shang hai ;*.
