Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cach thuc » anh thuc, cac thu
van hanh » van thanh, ban hanh, van anh
hieu ve » hieu va, hieu van
va hanh » va thanh, va danh, ban hanh
nong x » nong xa, nang x, nong e
ve cam » ve cham, ve cac, va cam
vi cua » vai cua, di cua
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: su ((cach tu) OR (cach thuc)) nong x hoi. hieu ve cam xuc ((va hanh) or (van hanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((cach tu) OR (cach thuc)) nong x hoi. hieu ve cam xuc ((va hanh) OR (van hanh)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((cach tu) OR (cach thuc)) nong x hoi. hieu ve cam xuc ((va hanh) or (van hanh)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su ((cach tu) OR (cach thuc)) nong x hoi. hieu ve cam xuc ((va hanh) or (van hanh)) vi cua triet*.
