Perhaps you should try some spelling variations:
hanh di » hanh vi, hanh de, hang di
sach ty » sach y, sach thu, xach tay
hieu va » lieu va, hieu qua
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
sach tu » sach thu, cach tu, sach uu
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
di cuu » di cau, di cua, dinh cuu
va cam » va cham, va cac, va cao

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