Answer 1

I think you are probably looking for:

Redirect 301 /keyword_city.html /keyword-city.html

to be placed in your .htaccess file.

As other people have mentioned though, probably not going to help a great deal when it comes to SEO. One thing that could however is using rich snippets/structured data:

Can be a lot of effort to do but would really help your presence on Google especially.

添加到.htacess的以下代码应将所有下划线_重定向到连字符-

RewriteRule (.*)_(.*) $1-$2 [N]
