Perhaps you should try some spelling variations:
sach thu » sach thue, sach thieu, sach tham
sach ty » sach y, sach tu, xach tay
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
cao xuc » cao duc, cao suc, chat xuc
cuu tre » cua tre, cau tren, cau treo
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
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 ty) or (sach thu)) lang xa hoi. hieu va ((cao xuc) OR (cam xuc)) va hanh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach thu)) lang xa hoi. hieu va ((cao xuc) OR (cam xuc)) va hanh di cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach thu)) lang xa hoi. hieu va ((cao xuc) OR (cam xuc)) va hanh di cuu tre*".
