Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, van anh, van ban
ban hanh » ban hang
cua tre » cua te, cuu tre, dua tren
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
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 cac xuc ((van hanh) OR (ban 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 cac xuc ((van hanh) OR (ban hanh)) di ((cua tre) or (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu ve cac xuc ((van hanh) OR (ban hanh)) di ((cua tre) or (cua triet))*.
