Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
cua tre » cua te, cua triet, dua tren
tinh di » tinh doi, trinh di, tinh da
va tinh » may tinh
cua tuc » cua duc, cua tu, cua thuoc
cua xuc » cua duc, cua cuc, cua nuoc
tang xa » trang xa, tang ma, lang xa
ty tang » tay tang, ty xang, ty hang
cuu tre » cau tren, cau treo

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 ty tang xa hoi. nhieu viec ((cua xuc) OR (cua tuc)) va tinh di ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty tang xa hoi. nhieu viec ((cua xuc) OR (cua tuc)) va tinh di ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty tang xa hoi. nhieu viec ((cua xuc) OR (cua tuc)) va tinh di ((cua tre) or (cuu tre))*".
