Perhaps you should try some spelling variations:
dong hoang » hong hong
dong yang » wang yang, dan yang, dong jung
yang yang » wang yang, wang yan
shang hai » shang kai, dang hai, chang ha
ka chuan » say chuan, hai chuan, ka chai
yang jun » yang jui, pang jun, yang jin
ka hua » ya hua

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((dong yang) OR (dong hoang))) or (yang yang)) ((ka hua) or (ka chuan)) rene yang jun shang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong yang) OR (dong hoang))) OR (yang yang)) ((ka hua) OR (ka chuan)) rene yang jun shang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yang) OR (dong hoang))) or (yang yang)) ((ka hua) or (ka chuan)) rene yang jun shang hai ;".
• Adding a wildcard symbol may retrieve word variants: ((((dong yang) OR (dong hoang))) or (yang yang)) ((ka hua) or (ka chuan)) rene yang jun shang hai ;*.
