Perhaps you should try some spelling variations:
ban hanh » ban hang
ve triet » va trien, su triet
vu sach » vu bach, su sach, vu khach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cao luc » bao luc, cao duc, cao suc
va hanh » van hanh, va thanh, dao hanh
va danh » va dinh, va dan, dia danh
y nang » ky nang, ly nang, v nang
va cao » va cac, va co, va dao
ca ve » ca va, va ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sach y nang xa hoi. hieu va cao luc ((((va hanh) or (ban hanh))) or (va danh)) ca ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang xa hoi. hieu va cao luc ((((va hanh) OR (ban hanh))) OR (va danh)) ca ve triet.
• Adding a wildcard symbol may retrieve word variants: vu sach y nang xa hoi. hieu va cao luc ((((va hanh) or (ban hanh))) or (va danh)) ca ve triet*.
