Perhaps you should try some spelling variations:
dong hoang » hong hong
dong yang » wang yang, yang yang, dan yang
than daun » than bau, than daem, than data
can tata » can data, can take, can tax
yang ii » yang di, yang xi, yang yi
how hai » how has, how ai, how hci
ii how » iii how

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)) ka ((than daun) OR (can tata)) yang ii how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) OR (dong hoang)) ka ((than daun) or (can tata)) yang ii how hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong yang) OR (dong hoang)) ka ((than daun) or (can tata)) yang ii how hai ;*.
