Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van thanh » ban thanh, van tuan
van hanh » ban hanh, van anh, van ban
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
cua tre » cua te, cuu tre, dua tren
ve cac » va cac, vien cac

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 cac ky lang xa hoi. hieu ve cac xuc ((van hanh) OR (van thanh)) di ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky lang xa hoi. hieu ve cac xuc ((van hanh) OR (van thanh)) di ((cua tre) or (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky lang xa hoi. hieu ve cac xuc ((van hanh) OR (van thanh)) di ((cua tre) or (cua triet))*.
