Perhaps you should try some spelling variations:
thuat sac » thuat sach, thuat san, thuat tac
hanh vai » hanh vi, hanh va, hanh tai
su triet » su viet, su tien
ve triet » va trien
nang xa » nang x, lang xa, nang ma
cac tuc » cac toc, cac tu, cac tac
xa hanh » xa thanh, xa khanh, va hanh
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 ((((su triet) OR (ve 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 ((((su triet) OR (ve 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 ((((su triet) OR (ve 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 ((((su triet) OR (ve triet))) or (cua te))*.
