Perhaps you should try some spelling variations:
cau treo » cau theo, cau tren, cau triet
van hanh » van thanh, ban hanh, van anh
cuu tre » cua tre, cau tren
hanh di » hanh vi, hanh de, hang di
xuc van » duc van, luc van, vuc van
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach 2, sach vay
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 v) or (sach y)) nang xa hoi. hieu ve cam xuc van hanh di ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach y)) nang xa hoi. hieu ve cam xuc van hanh di ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach y)) nang xa hoi. hieu ve cam xuc van hanh di ((cuu tre) OR (cau treo))*".
