Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vi » hanh vi, thanh va, thanh ve
va thanh » gia thanh, ban thanh, va tinh
cua tre » cua te, cuu tre, dua tren
van lam » van nam
van cam » van nam, van cau, van dam
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
su sac » su sach, su cac, su xac

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: su sac ky lang xa hoi. hieu ((van cam) OR (van lam)) xuc va thanh vi ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky lang xa hoi. hieu ((van cam) or (van lam)) xuc va thanh vi ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: su sac ky lang xa hoi. hieu ((van cam) or (van lam)) xuc va thanh vi ((cua tre) OR (cua triet))*.
