Perhaps you should try some spelling variations:
cau treo » cau theo, cau tren, cau triet
cham xuc » chat xuc, cham soc, pham duc
sach tay » xach tay, sach hay, sach nay
hieu van » hieu va, thien van, lieu va
lang ha » long ha
lang xa » dang xay, lang van
va hang » van hang, va nang, va lang
hang di » hang doi, hang vi, hang dien
so sach » so sanh, bo sach, co sach
di cau » da cau, diem cau

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach tay ((lang xa) OR (lang ha)) hoi. hieu van ((cham xuc) or (cam xuc)) va hang di cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach tay ((lang xa) OR (lang ha)) hoi. hieu van ((cham xuc) OR (cam xuc)) va hang di cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach tay ((lang xa) OR (lang ha)) hoi. hieu van ((cham xuc) or (cam xuc)) va hang di cau treo*".
