Perhaps you should try some spelling variations:
hanh va » hang va, hanh vi
va hanh » van hanh, va thanh, va danh
nam xua » nam cua, nam mua, nam qua
sach ky » sach y, sach ty, sach kem
nam xuc » cam xuc, nam thuc, nam duoc
lang xa » lang ha, dang xay, lang van
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky, sai ky
va cua » va chua, via cua, ca 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: su ((sach ky) OR (sac ky)) lang xa hoi. lieu va ((nam xuc) OR (nam xua)) va hanh va cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sac ky)) lang xa hoi. lieu va ((nam xuc) OR (nam xua)) va hanh va cua tre~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (sac ky)) lang xa hoi. lieu va ((nam xuc) OR (nam xua)) va hanh va cua tre*.
