Perhaps you should try some spelling variations:
thuat van » thuat san, thuat va, thuat ban
va triet » va thiet, va trien, cua triet
ve triet » va trien, su triet
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cao xuc » cam xuc, cao duc, cao suc
va vanh » va danh, va hanh, va anh
va cao » va cac, va co, va dao

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

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