Perhaps you should try some spelling variations:
va triet » va thiet, va trien, ve triet
sach thu » sach thue, sach thieu, sach tham
hieu van » hieu va, thien van, lieu va
va hanh » van hanh, va thanh, va danh
sach ty » sach y, sach tu, xach tay
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va
xuc va » duc va, tuc va, luc va
vi va » vi van, vai va, vu va

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

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