Perhaps you should try some spelling variations:
vinh cuu » dinh cuu, sinh cua, dinh cu
te sach » toc sach
nam tuc » nam thuc, nam truc, nam thuoc
xa hanh » xa thanh, xa khanh, va hanh
hieu va » lieu va, hieu qua
nang ma » tang ma, sang ma, nang cao
y nang » ky nang, ly nang, v nang
nam tu » nam thu, nam thuc
ma hoi » mai hoi, xa hoi, ma hoa
vi cuu » vi luu

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 y nang ma hoi. hieu va ((nam tuc) or (nam tu)) xa hanh ((vi cuu) OR (vinh cuu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. hieu va ((nam tuc) OR (nam tu)) xa hanh ((vi cuu) OR (vinh cuu)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. hieu va ((nam tuc) or (nam tu)) xa hanh ((vi cuu) OR (vinh cuu)) tre*".
