Perhaps you should try some spelling variations:
cuc triet » cua triet, su triet, cac trieu
va thanh » gia thanh, ban thanh, va tinh
cac thuc » cach thuc, cac thu, can thuc
thi hanh » thi thanh
thi nang » thi cong, ki nang
va hanh » van hanh, va danh, ban hanh
te sach » toc sach
x hoi » xa hoi, o hoi, x ho

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 ((thi nang) OR (thi hanh)) x hoi. lieu va cac thuc ((va hanh) or (va thanh)) tai cuc triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thi nang) OR (thi hanh)) x hoi. lieu va cac thuc ((va hanh) OR (va thanh)) tai cuc triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thi nang) OR (thi hanh)) x hoi. lieu va cac thuc ((va hanh) or (va thanh)) tai cuc triet".
• Adding a wildcard symbol may retrieve word variants: te sach ((thi nang) OR (thi hanh)) x hoi. lieu va cac thuc ((va hanh) or (va thanh)) tai cuc triet*.
