Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
lai cuu » lai cua, lai chau, lai cuoc
anh lai » anh bai, anh tai, gianh lai
cuu tre » cua tre, cau tren, cau treo
y lang » _ lang, tay lang, yen lang
va cam » va cham, va cac, va cao
o lang » hoa lang, hoi lang
va anh » van anh, va danh, va hanh
ve cai » va cai, ve cac, ve tai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y lang) OR (o lang)) xa hoi. hieu ((ve cai) or (va cam)) duc va anh lai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y lang) OR (o lang)) xa hoi. hieu ((ve cai) OR (va cam)) duc va anh lai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y lang) OR (o lang)) xa hoi. hieu ((ve cai) or (va cam)) duc va anh lai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y lang) OR (o lang)) xa hoi. hieu ((ve cai) or (va cam)) duc va anh lai cuu tre*.
