Perhaps you should try some spelling variations:
dong hoang » hong hong
dong yang » wang yang, yang yang, dan yang
lang hua » wang hua, wang hui, dong hua
hua rest » hua ren
ying jin » yang jin, jing ji, yang jie
keong yu » hong yu, rong yu
jeong su » jeong _, jeong mi, jeong 情

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 yang) OR (dong hoang)) lang hua rest ying jin ((keong yu) OR (jeong su)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) OR (dong hoang)) lang hua rest ying jin ((keong yu) or (jeong su)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong yang) OR (dong hoang)) lang hua rest ying jin ((keong yu) or (jeong su)) ;*.
