Perhaps you should try some spelling variations:
nhien cam » nghiep cam, nhien dai, nhien va
khanh van » thanh van, khanh vinh, hanh va
su triet » su viet, ve triet
te sach » toc sach
su tien » su kien, su hien, tu tieng
sach ty » sach y, sach tu, sach thu
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
tuc va » thuc va, truc va, tuc xa
xuc va » duc va, luc va, xac va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty nang xa hoi. thien nhien cam ((xuc va) OR (tuc va)) khanh van ((su triet) or (su tien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. thien nhien cam ((xuc va) OR (tuc va)) khanh van ((su triet) OR (su tien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. thien nhien cam ((xuc va) OR (tuc va)) khanh van ((su triet) or (su tien))".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. thien nhien cam ((xuc va) OR (tuc va)) khanh van ((su triet) or (su tien))*.
