Perhaps you should try some spelling variations:
va triet » va thiet, va trien, ve triet
thu nang » thi nang, thu hang, thu bang
ban hanh » ban hang
va hanh » van hanh, va thanh, va danh
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cao xuc » cam xuc, cao duc, chat xuc
cac thu » cach thuc, cac thoi
cao suc » cao su, cao duc
su cac » tu cac, su cao, su can
vi va » vi van, vai va, vu va

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

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