Perhaps you should try some spelling variations:
ve triet » va trien, su triet
trang va » tran van, hang va
trung va » truong va, trung ha, trung tam
danh vi » hanh vi, dinh vi, danh di
vu sach » vu bach, su sach, vu khach
sach lo » sach dao, sach doi, sach hoi
hieu va » lieu va, hieu qua
hieu ve » hieu van
nang xa » nang x, lang xa, nang ma
lo nang » ho nang, ly nang, loai nang
vi ve » va ve, gi ve, ve ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sach lo nang xa hoi. ((hieu ve) or (hieu va)) cau ((trung va) OR (trang va)) danh vi ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach lo nang xa hoi. ((hieu ve) OR (hieu va)) cau ((trung va) OR (trang va)) danh vi ve triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach lo nang xa hoi. ((hieu ve) or (hieu va)) cau ((trung va) OR (trang va)) danh vi ve triet*".
