Perhaps you should try some spelling variations:
va triet » va thiet, va trien, ve triet
sach ty » sach y, sach tu, sach thu
dinh cu » dinh cuu, dinh chuc, dinh chau
dinh tu » danh tu, tinh tu, dinh du
thuc va » thuc vat, thuc dan, thuc day
te sach » toc sach
ty nang » ky nang, ty xang, ty hang
hieu ve » hieu va, hieu van
xuc va » duc va, tuc va, luc va
ve cam » ve cham, ve cac, va cam
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 sach ty nang x hoi. hieu ve cam ((xuc va) or (thuc va)) ((dinh tu) OR (dinh cu)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang x hoi. hieu ve cam ((xuc va) OR (thuc va)) ((dinh tu) OR (dinh cu)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang x hoi. hieu ve cam ((xuc va) or (thuc va)) ((dinh tu) OR (dinh cu)) va triet".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang x hoi. hieu ve cam ((xuc va) or (thuc va)) ((dinh tu) OR (dinh cu)) va triet*.
