Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
shang hai » shang kai, dang hai, chang ha
tan chia » tuan china, dan china, han china
dan yang » daun yang, tan yang, wang yang
li shang » li zhang, wei shang, xia shang
wan yan » wang yan, nan yan, wai yan
yang li » yang lin, yang di, yang xi

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: wan yan ((((tan chia) OR (than china))) OR (can china)) dan yang li shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((((tan chia) OR (than china))) or (can china)) dan yang li shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ((((tan chia) OR (than china))) or (can china)) dan yang li shang hai ;*.
