Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
ban hanh » ban hang
cham xuc » cam xuc, chat xuc, cham soc
ve cham » va cham, ve chat, vu cham
xuc ban » duc ban, cuc ban, quoc ban
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
ky tang » ky nang, ky dang, kho tang
hieu ve » hieu va, hieu van
ma hoi » mai hoi, ma hoa, me hoi

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 ky tang ((ma hoi) or (xa hoi)). hieu ve cham xuc ban hanh vi ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky tang ((ma hoi) OR (xa hoi)). hieu ve cham xuc ban hanh vi ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky tang ((ma hoi) or (xa hoi)). hieu ve cham xuc ban hanh vi ((cua triet) OR (cua viet))*".
