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

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