Perhaps you should try some spelling variations:
sach ky » sach y, sach ty, sach kem
lang xa » lang ha, dang xay, lang van
hieu va » lieu va
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) lang xa hoi. ((hieu va) OR (hieu qua)) cam xuc va hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) lang xa hoi. ((hieu va) or (hieu qua)) cam xuc va hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) lang xa hoi. ((hieu va) or (hieu qua)) cam xuc va hanh vi cua tre*.
