Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh than » hanh han, hanh nhan, hanh phan
van hanh » van thanh, ban hanh, van anh
cac xuc » cam xuc, cac nuoc, chat xuc
cua tre » cua te, cuu tre, dua tren
xuc van » duc van, luc van, vuc van
hieu ve » hieu va, hieu van
tu bat » tu dat
nang o » nang co, nang ho, nang ro
tu ban » thu ban, te ban
ve cac » va cac, vien cac
o lai » o lao

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 bat) OR (tu ban)) ky nang o lai. hieu ve cac xuc van hanh than ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu bat) or (tu ban)) ky nang o lai. hieu ve cac xuc van hanh than ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: ((tu bat) or (tu ban)) ky nang o lai. hieu ve cac xuc van hanh than ((cua tre) OR (cua triet))*.
