Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » thien van, lieu va, hieu ve
tham luu » tam luu, thanh luu, cham cuu
hanh vai » hanh vi, hanh tai, hanh van
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
luu dan » luu van, luu hanh, luat dan
hanh va » hang va, hanh vi

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

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