Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
xuc van » luc van, xuc ban, thuc van
duc van » duc va, duc tan, duc manh
hanh di » hanh vi, hanh de, hang di
cuu tre » cua tre, cau tren, cau treo
sach v » sach va, sach 2, sach vay
ve cac » va cac, vien cac
di cuu » di cau, di cua, dinh cuu

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