Perhaps you should try some spelling variations:
ban anh » ban hanh, ban banh, ban danh
xuc ban » duc ban, cuc ban, quoc ban
sach ky » sac ky, sach y, sach ty
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
ve cac » va cac, vien cac
va cuu » va cau, va chu
va huu » vu huu
x hoi » xa hoi, o hoi, x ho

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 ky) or (cac ky)) nang x hoi. hieu ve cac xuc ban anh ((va cuu) OR (va huu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (cac ky)) nang x hoi. hieu ve cac xuc ban anh ((va cuu) OR (va huu)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (cac ky)) nang x hoi. hieu ve cac xuc ban anh ((va cuu) OR (va huu)) tre*".
