Perhaps you should try some spelling variations:
nhung hoang » khung hoang, phuong hoang, nhung cong
hoang van » hang va
30 trieu » 25 trieu
trung va » truong va, trung ha, trung tam
trang va » tran van, hang va
van than » van thanh, van thang, van tuan
than cao » toan cao, thai cao, than cap

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: 30 trieu tinh - hanh ((((trung va) OR (trang va))) OR (truong dai)) nhung hoang van than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "30 trieu tinh - hanh ((((trung va) OR (trang va))) or (truong dai)) nhung hoang van than cao~".
• Adding a wildcard symbol may retrieve word variants: 30 trieu tinh - hanh ((((trung va) OR (trang va))) or (truong dai)) nhung hoang van than cao*.
