Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
ban thanh » ban hanh, ban hang
pham cuc » pham chuc, pham duc, pham cua
cham cuu » cap cuu, chat cua
sach ty » sach y, sach thu, xach tay
hieu va » lieu va, hieu qua
xang xa » lang xa, mang xa, ang xa
sach tu » sach thu, cach tu, sach uu
cua te » cua tu

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: toc ((sach ty) OR (sach tu)) xang xa hoi. hieu va ((cham cuu) OR (pham cuc)) ban thanh dai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ty) OR (sach tu)) xang xa hoi. hieu va ((cham cuu) or (pham cuc)) ban thanh dai cua te~".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ty) OR (sach tu)) xang xa hoi. hieu va ((cham cuu) or (pham cuc)) ban thanh dai cua te*.
