Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh tai » thanh hai, thanh toan, doanh tai
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cuc ban » cua ban, cuu ban, duc ban
cac ban » cac dan, cac van, can ban
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang xa hoi. hieu ve cam ((cuc ban) OR (cac ban)) thanh tai ((cua triet) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ve cam ((cuc ban) OR (cac ban)) thanh tai ((cua triet) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ve cam ((cuc ban) OR (cac ban)) thanh tai ((cua triet) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ve cam ((cuc ban) OR (cac ban)) thanh tai ((cua triet) or (cuu tre))*.
