Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
vai cuu » vai cua
cuu tre » cua tre, cau tren, cau treo
sang ma » tang ma, nang ma, sang tao
sach ty » sach tu, sach thu, xach tay
ma hoi » mai hoi, xa hoi, ma hoa
va bao » va bai
va bay » van bay, va bai, va ban

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) or (sach ty)) sang ma hoi. hieu ((va bay) OR (va bao)) dia ban thanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach y) OR (sach ty)) sang ma hoi. hieu ((va bay) OR (va bao)) dia ban thanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach y) or (sach ty)) sang ma hoi. hieu ((va bay) OR (va bao)) dia ban thanh vai cuu tre*".
