Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
ve triet » va trien, su triet
va triet » va thiet, va trien, cua triet
cam cuc » cam xuc, cham cuu, pham cuc
cuc ban » cua ban, cac ban, cuu ban
sach ky » sach y, sach ty, sach kem
hieu va » lieu va, hieu qua
nang ma » tang ma, sang ma, nang cao
ma hoi » mai hoi, xa hoi, ma hoa
sac ky » cac ky, sai ky
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: tu ((sach ky) or (sac ky)) nang ma hoi. hieu va cam cuc ban thanh vai ((va triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) nang ma hoi. hieu va cam cuc ban thanh vai ((va triet) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sac ky)) nang ma hoi. hieu va cam cuc ban thanh vai ((va triet) OR (ve triet))*".
