Perhaps you should try some spelling variations:
cau triet » cau trieu, su triet, cua triet
tinh san » trinh san, tinh sang, tinh son
toc sach » hoc sach, doc sach, thuoc sach
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, xac va
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc sach y nang xa hoi. hieu ve cham ((xuc va) OR (luc va)) tinh san ((cua tre) or (cau triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y nang xa hoi. hieu ve cham ((xuc va) OR (luc va)) tinh san ((cua tre) OR (cau triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y nang xa hoi. hieu ve cham ((xuc va) OR (luc va)) tinh san ((cua tre) or (cau triet))".
• Adding a wildcard symbol may retrieve word variants: toc sach y nang xa hoi. hieu ve cham ((xuc va) OR (luc va)) tinh san ((cua tre) or (cau triet))*.
