Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, le thanh
va tinh » may tinh
cam luc » cam xuc, cau luc
hieu va » lieu va, hieu qua
hieu ve » hieu van
sac ky » cac ky, sai ky
vi cua » vai cua, di cua
te sac » te sach, te cac, te san

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: te sac ky nang x ho. ((hieu ve) OR (hieu va)) cam luc ((va thanh) OR (va tinh)) vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x ho. ((hieu ve) OR (hieu va)) cam luc ((va thanh) or (va tinh)) vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x ho. ((hieu ve) OR (hieu va)) cam luc ((va thanh) or (va tinh)) vi cua triet*.
