Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ban hanh » ban hang
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu va » lieu va, hieu qua
cham so » cham soc, ham so, cham hoi
cham o » cham soc
vi cua » vai cua, di cua

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky tang xa hoi. hieu va ((cham so) OR (cham o)) ban hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky tang xa hoi. hieu va ((cham so) OR (cham o)) ban hanh vi cua triet*.
