Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
ban hang » ngan hang
van nhan » van phan, van thanh, danh nhan
nhan luc » nang luc
nang xa » nang x, lang xa, nang ma
va danh » va dinh, va dan, va hanh
cai ky » cao ky, cam ky, sai ky
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((cai ky) OR (cac ky)) nang xa hoi. hieu van nhan luc ((ban hang) or (va danh)) di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((cai ky) OR (cac ky)) nang xa hoi. hieu van nhan luc ((ban hang) OR (va danh)) di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((cai ky) OR (cac ky)) nang xa hoi. hieu van nhan luc ((ban hang) or (va danh)) di cua triet".
• Adding a wildcard symbol may retrieve word variants: tu ((cai ky) OR (cac ky)) nang xa hoi. hieu van nhan luc ((ban hang) or (va danh)) di cua triet*.
