Perhaps you should try some spelling variations:
ve triet » va trien, su triet
va danh » va dinh, va dan, dia danh
va hanh » van hanh, va thanh, ban hanh
sach ty » sach y, sach tu, sach thu
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
sang ma » tang ma, nang ma, sang tao
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
va ve » va de, va le, va vi

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty ((nang xa) or (sang ma)) hoi. hieu ve cam xuc ((va hanh) OR (va danh)) va ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ((nang xa) OR (sang ma)) hoi. hieu ve cam xuc ((va hanh) OR (va danh)) va ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((nang xa) or (sang ma)) hoi. hieu ve cam xuc ((va hanh) OR (va danh)) va ve triet".
• Adding a wildcard symbol may retrieve word variants: so sach ty ((nang xa) or (sang ma)) hoi. hieu ve cam xuc ((va hanh) OR (va danh)) va ve triet*.
