Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ban hanh » ban hang
chat xuc » chat huu, cam xuc, chao xu
cac xuc » cam xuc, cac nuoc, cac cuoc
sach ty » sach y, sach tu, sach thu
tu sach » thu sach, su sach, te sach
mai hoi » mai khoi, dai hoi, lai hoi
ty nang » ky nang, ty xang, ty hang
hieu ve » hieu va, hieu van
ma hoi » xa hoi, ma hoa, me hoi
vi cua » vai cua, di cua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang ((ma hoi) OR (mai hoi)). hieu ve ((cac xuc) OR (chat xuc)) ban hanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang ((ma hoi) OR (mai hoi)). hieu ve ((cac xuc) or (chat xuc)) ban hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang ((ma hoi) OR (mai hoi)). hieu ve ((cac xuc) or (chat xuc)) ban hanh vi cua triet*.
