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

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