Perhaps you should try some spelling variations:
yuan ting » yuan ming, huang ting, yuan kang
yang amin » yang lin
yang mind » yang cindy, sang minh, tang min
tan chia » tuan china, than china, can china
chia ban » chia lan, chia wen, hua ban
yang jin » yang jie, yang jun, ying jin
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: ((yuan ting) OR (wang yan)) tan chia ban ((((yang amin) OR (yang jin))) OR (yang mind)) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan ting) or (wang yan)) tan chia ban ((((yang amin) OR (yang jin))) or (yang mind)) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan ting) or (wang yan)) tan chia ban ((((yang amin) OR (yang jin))) or (yang mind)) hong hai ;*.
