Perhaps you should try some spelling variations:
nhan thuc » nhan luc, dan thuc, toan thuc
nham thuc » nam thuc, nham thu, pham thuc
dan danh » van danh, han danh, ban danh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
dau su » dau tu, da su, dat su
dan su » dang su

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky lang xa hoi. lieu va ((nham thuc) or (nhan thuc)) dan danh ((dau su) OR (dan su)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky lang xa hoi. lieu va ((nham thuc) OR (nhan thuc)) dan danh ((dau su) OR (dan su)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky lang xa hoi. lieu va ((nham thuc) or (nhan thuc)) dan danh ((dau su) OR (dan su)) triet".
• Adding a wildcard symbol may retrieve word variants: tu cac ky lang xa hoi. lieu va ((nham thuc) or (nhan thuc)) dan danh ((dau su) OR (dan su)) triet*.
