Perhaps you should try some spelling variations:
ve triet » va trien, su triet
danh ve » dinh ve, hanh ve, anh ve
thuc va » thuc vat, thuc dan, thuc day
hieu ve » hieu va, hieu van
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
te cac » tu cac, te cao, de cac
te sac » te sach, te san
x hoi » xa hoi, o hoi, x ho
ve ve » de ve, va ve, ke ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((te sac) OR (te cac)) ky nang x hoi. hieu ve cac ((xuc va) or (thuc va)) danh ve ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te cac)) ky nang x hoi. hieu ve cac ((xuc va) OR (thuc va)) danh ve ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te cac)) ky nang x hoi. hieu ve cac ((xuc va) or (thuc va)) danh ve ve triet".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te cac)) ky nang x hoi. hieu ve cac ((xuc va) or (thuc va)) danh ve ve triet*.
