Perhaps you should try some spelling variations:
sach tay » xach tay, sach nay, sach tai
sach hay » sach han, sach ha, sach nay
cham xuc » chat xuc, cham soc, pham duc
hieu van » hieu va, thien van, lieu va
hang di » hang doi, hang vi, hang dien
va hang » van hang, va nang, va lang
lang xa » lang ha, dang xay, lang van
cuu tre » cua tre, cau tren, cau treo
di cuu » di cau, di cua, dinh cuu

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 tay) OR (sach hay)) lang xa hoi. hieu van ((cham xuc) OR (cam xuc)) va hang di cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach tay) OR (sach hay)) lang xa hoi. hieu van ((cham xuc) or (cam xuc)) va hang di cuu tre~".
• Adding a wildcard symbol may retrieve word variants: su ((sach tay) OR (sach hay)) lang xa hoi. hieu van ((cham xuc) or (cam xuc)) va hang di cuu tre*.
