Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
van hanh » van thanh, van anh, van ban
ban hanh » ban hang
su triet » su viet, su tien, ve triet
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao

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

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