Perhaps you should try some spelling variations:
su triet » su tien, ve triet
hieu ve » hieu va, hieu van
thuc va » thuc vat, thuc dan, thuc day
danh ve » dinh ve, hanh ve, anh ve
su viet » so viet
te cac » tu cac, ve cac, te cao
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

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

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