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

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