Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
van hanh » van thanh, ban hanh, van anh
hanh tri » thanh tri, hanh tai, hanh trinh
va triet » va thiet, va trien, ve triet
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
xuc van » duc van, luc van, vuc van
bai ky » ban ky, sai ky, dai ky
bac ky » cac ky, ban ky, sac 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: te ((bai ky) OR (bac ky)) nang xa hoi. hieu va cam xuc van hanh tri ((cua triet) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((bai ky) OR (bac ky)) nang xa hoi. hieu va cam xuc van hanh tri ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((bai ky) OR (bac ky)) nang xa hoi. hieu va cam xuc van hanh tri ((cua triet) or (va triet))".
• Adding a wildcard symbol may retrieve word variants: te ((bai ky) OR (bac ky)) nang xa hoi. hieu va cam xuc van hanh tri ((cua triet) or (va triet))*.
