Perhaps you should try some spelling variations:
dong sein » dong sin, dong bin, dong wei
sein bonn » klein bonn, sein dann, sein kann
iii where » ii where, i where, iii wege
where guo » where do, where sun, where obo
bonn iii » bonn die, bonn ein, sinn iii
guo ming » guo jing, guo xin, guo feng
yang jui » yang judy, yang xi
yang yi » 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: dong sein bonn iii where guo ming ((((yang dean) OR (yang jui))) OR (((yang di) OR (yang yi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong sein bonn iii where guo ming ((((yang dean) or (yang jui))) or (((yang di) or (yang yi)))) ;*.
