Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc dan » thuc hanh, hoc dan, thuc vat
thuc va » thuc vat, thuc day
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
sach v » sach va, sach y, sach 2
v nang » va nang, vu nang, van nang
vi cua » vai cua, di cua

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: te sach v nang xa hoi. ((hieu ve) OR (hieu qua)) can ((thuc va) OR (thuc dan)) hanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. ((hieu ve) or (hieu qua)) can ((thuc va) OR (thuc dan)) hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach v nang xa hoi. ((hieu ve) or (hieu qua)) can ((thuc va) OR (thuc dan)) hanh vi cua triet*.
