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