Perhaps you should try some spelling variations:
te sach » toc sach
ty nang » ty xang, ty hang, ly nang
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
va hanh » van hanh, va thanh, va danh
ve cam » ve cham, ve cac, va cam
tuc va » thuc va, truc va, tuc xa
vi va » vi van, vai va, bi va
vu va » vu van, tu va, su va

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) or (ky nang)) xa hoi. hieu ve cam tuc va hanh ((vi va) OR (vu va)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ky nang)) xa hoi. hieu ve cam tuc va hanh ((vi va) OR (vu va)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) or (ky nang)) xa hoi. hieu ve cam tuc va hanh ((vi va) OR (vu va)) triet*".
