Perhaps you should try some spelling variations:
thuat sac » thuat sach, thuat san, thuat tac
hanh vai » hanh vi, hanh tai, hanh van
su triet » su viet, su tien, ve triet
nang xa » nang x, lang xa, nang ma
cac tuc » cac toc, cac tu, cac tac
hanh va » hang va, hanh vi
sac ky » cac ky, sai ky
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. lieu va cac tuc xa ((hanh vai) OR (hanh va)) ((su triet) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sac ky nang xa hoi. lieu va cac tuc xa ((hanh vai) OR (hanh va)) ((su triet) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sac ky nang xa hoi. lieu va cac tuc xa ((hanh vai) OR (hanh va)) ((su triet) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: thuat sac ky nang xa hoi. lieu va cac tuc xa ((hanh vai) OR (hanh va)) ((su triet) or (cua te))*.
