Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
cac xuc » cam xuc, cac nuoc, chat xuc
cua tre » cua te, cuu tre, dua tren
hanh di » hanh vi, hanh de, hang di
xuc van » duc van, luc van, xuc ban
hieu va » lieu va, hieu qua
hieu ve » hieu van
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu 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: tu sac ky lang xa hoi. ((hieu ve) OR (hieu va)) cac xuc van hanh di ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. ((hieu ve) OR (hieu va)) cac xuc van hanh di ((cua tre) or (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. ((hieu ve) OR (hieu va)) cac xuc van hanh di ((cua tre) or (cua triet))*.
