Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh tai » thanh hai, thanh toan, doanh tai
ban thanh » ban hanh, ban hang
cuu tre » cua tre, cau tren, cau treo
cuc ban » cua ban, cac ban, cuu ban
cam cuc » cam xuc, cham cuu, pham cuc
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
sac ky » cac 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) OR (sai ky)) nang xa hoi. hieu ve cam cuc ban thanh tai ((cua triet) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sai ky)) nang xa hoi. hieu ve cam cuc ban thanh tai ((cua triet) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (sai ky)) nang xa hoi. hieu ve cam cuc ban thanh tai ((cua triet) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) OR (sai ky)) nang xa hoi. hieu ve cam cuc ban thanh tai ((cua triet) or (cuu tre))*.
