Perhaps you should try some spelling variations:
thuat sac » thuat sach, thuat san, thuat tac
cua triet » cua viet, su triet, va triet
hanh vai » hanh vi, hanh va, hanh tai
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc va
cua te » cua tu

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

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