Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va hanh » van hanh, va thanh, ban hanh
nang ma » tang ma, sang ma, nang cao
ve cham » va cham, ve chat, vu cham
va danh » va dinh, va dan, dia danh
vi cua » vai cua, di cua
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ma hoi » mai hoi, xa hoi, ma hoa
ve cac » va cac, vien cac

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

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