Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
va triet » va thiet, va trien, ve triet
cuc ban » cua ban, cac ban, cuu ban
cam cuc » cam xuc, cham cuu, pham cuc
sach ky » sac ky, sach y, sach ty
hieu va » lieu va
nang xa » nang x, lang xa, nang ma
sai ky » sac ky
vai va » mai va, dai va, hai va

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 (sai ky)) nang xa hoi. ((hieu va) OR (hieu qua)) cam cuc ban thanh vai va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sai ky)) nang xa hoi. ((hieu va) OR (hieu qua)) cam cuc ban thanh vai va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sai ky)) nang xa hoi. ((hieu va) OR (hieu qua)) cam cuc ban thanh vai va triet*".
