Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh vai » hanh vi, hanh va, hanh tai
dang xay » dang van, van xay
van hanh » van thanh, ban hanh, van anh
xuc van » duc van, luc van, vuc van
cua tre » cua te, cuu tre, dua tren
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam

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 sach y ((nang xa) OR (dang xay)) hoi. hieu ve cam xuc van hanh vai ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ((nang xa) or (dang xay)) hoi. hieu ve cam xuc van hanh vai ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: su sach y ((nang xa) or (dang xay)) hoi. hieu ve cam xuc van hanh vai ((cua tre) OR (cua triet))*.
