Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
va cham » va chat, va tham
va hanh » va thanh, va danh, ban hanh
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
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 sac ky nang x hoi. hieu ((ve cam) or (va cham)) thuc ((va hanh) OR (van hanh)) dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang x hoi. hieu ((ve cam) OR (va cham)) thuc ((va hanh) OR (van hanh)) dai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x hoi. hieu ((ve cam) or (va cham)) thuc ((va hanh) OR (van hanh)) dai cua triet*".
