Perhaps you should try some spelling variations:
cau theo » cau thi, cau tao
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, xuc ban
vuc van » duc van, luc van, thuc van
hang di » hang doi, hang vi, hang dien
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
ve cam » ve cham, ve cac, va cam

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 y nang xa hoi. hieu ve cam ((xuc van) OR (vuc van)) hang di ((cua tre) or (cau theo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu ve cam ((xuc van) OR (vuc van)) hang di ((cua tre) OR (cau theo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu ve cam ((xuc van) OR (vuc van)) hang di ((cua tre) or (cau theo))*".
