Perhaps you should try some spelling variations:
mein dank » ein dank, sein dann
chen wang » chen yang, chen rong, chen ping
wang minh » sang minh, kang minah, anh minh
dank jui » dank i, yang jui, dank vii
jui chen » yi chen
yang yi » yang di, yang jui
yang xi » 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: (dong OR doing) mein dank jui chen wang minh ((yang judy) OR (((yang yi) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: (dong or doing) mein dank jui chen wang minh ((yang judy) or (((yang yi) or (yang xi)))) ;*.
