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