Perhaps you should try some spelling variations:
ve triet » va trien, su triet
dinh de » dinh ve, dinh du, dinh le
thuc va » thuc vat, thuc dan, thuc day
hieu ve » hieu va, hieu van
ky dang » ky nang, ky danh
ky tang » ky nang, kho tang, ky trong
ma hoi » mai hoi, xa hoi, ma hoa
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
te sac » te sach, te cac, te san

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 ((ky tang) OR (ky dang)) ma hoi. hieu ve cam ((xuc va) or (thuc va)) dinh de ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ((ky tang) OR (ky dang)) ma hoi. hieu ve cam ((xuc va) OR (thuc va)) dinh de ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ((ky tang) OR (ky dang)) ma hoi. hieu ve cam ((xuc va) or (thuc va)) dinh de ve triet".
• Adding a wildcard symbol may retrieve word variants: te sac ((ky tang) OR (ky dang)) ma hoi. hieu ve cam ((xuc va) or (thuc va)) dinh de ve triet*.
