Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
va hanh » van hanh, va thanh, va danh
hieu va » lieu va, hieu qua
cam thu » nam thu, cac thu, cam phu
ca thu » cac thu, ca tru, va thu
vi cua » vai cua, di cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky

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 sac ky nang xa hoi. ((hieu ve) OR (hieu va)) ((cam thu) OR (ca thu)) va hanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. ((hieu ve) or (hieu va)) ((cam thu) OR (ca thu)) va hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. ((hieu ve) or (hieu va)) ((cam thu) OR (ca thu)) va hanh vi cua triet*.
