Perhaps you should try some spelling variations:
ban hanh » ban hang
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, dao hanh
va danh » va dinh, va dan, dia danh
lai cua » dai cua, hai cua, lai chau
cua chu » sua chua
nang o » nang co, nang ho, nang ro
ve cac » va cac, vien cac
o hoi » co hoi, o hoc, o hai

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 nang o hoi. hieu ve cac xuc ((((va hanh) OR (ban hanh))) or (va danh)) lai cua chu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang o hoi. hieu ve cac xuc ((((va hanh) OR (ban hanh))) OR (va danh)) lai cua chu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang o hoi. hieu ve cac xuc ((((va hanh) OR (ban hanh))) or (va danh)) lai cua chu".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang o hoi. hieu ve cac xuc ((((va hanh) OR (ban hanh))) or (va danh)) lai cua chu*.
