Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
hieu van » hieu va, thien van, lieu va
va hanh » van hanh, va thanh, va danh
hanh di » hanh vi, hanh de, hang di
tu sach » thu sach, su sach, te sach
hoa xuc » hoa xua, hoa xu, hoa duoc
sach v » sach va, sach y, sach 2
ha xuc » ha duc, chat xuc
v nang » va nang, vu nang, van nang

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 v nang x ho. hieu van ((ha xuc) OR (hoa xuc)) va hanh di ((cua triet) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v nang x ho. hieu van ((ha xuc) OR (hoa xuc)) va hanh di ((cua triet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v nang x ho. hieu van ((ha xuc) OR (hoa xuc)) va hanh di ((cua triet) or (va triet))*".
