Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thanh vai » thanh hai, thanh van, thanh tai
su triet » su viet, su tien, ve triet
sach thi » sach thu, sach tai, sach thieu
cua tre » cua te, cuu tre, cua triet
xuc ban » duc ban, cuc ban, quoc ban
su sach » so sach, vu sach
hieu va » lieu va, hieu qua
hang xa » hoang xa, hang ca, lang xa
va cam » va cham, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach thi ((hang xa) OR (hang va)) hoi. hieu va cam xuc ban thanh vai ((cua tre) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thi ((hang xa) OR (hang va)) hoi. hieu va cam xuc ban thanh vai ((cua tre) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thi ((hang xa) OR (hang va)) hoi. hieu va cam xuc ban thanh vai ((cua tre) or (su triet))*".
