Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
hanh ve » hanh vi, hanh va, hanh kem
hanh de » hanh kem
luc van » luoc van, luu van, duc van
cam luc » cam xuc, cau luc
hieu ve » hieu va
nang xa » nang x, lang xa, nang ma
sai ky » sac ky
te sai » te tai, te bai, te lai

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky nang xa hoi. ((hieu ve) OR (hieu van)) cam luc van ((hanh de) or (hanh ve)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky nang xa hoi. ((hieu ve) OR (hieu van)) cam luc van ((hanh de) OR (hanh ve)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky nang xa hoi. ((hieu ve) OR (hieu van)) cam luc van ((hanh de) or (hanh ve)) cua triet".
• Adding a wildcard symbol may retrieve word variants: te sai ky nang xa hoi. ((hieu ve) OR (hieu van)) cam luc van ((hanh de) or (hanh ve)) cua triet*.
