Expected behavior

I hope to hide the comment_count in post-meta of post.
(我希望能够隐藏文章前面的评论数)

Actual behavior

comment count only can be hidden in home page.
(只能够隐藏主页的评论数)

• Links to demo site with this feature: N/A
  This is my blog:
  (这是我的博客地址)
  [https: blog.xyang.xin](https: blog.xyang.xin)

Steps to reproduce the behavior

All are the latest.
(全部都是最新的)
No other comments plugins such as Disqus.
没有安装其他类似于 Disqus 的评论插件，只开启了 valine。

valine:
  enable: true
  appid: XXX
  appkey: XXX
  notify: true # Mail notifier
  verify: false # Verification code
  placeholder: Just go go # Comment box placeholder
  avatar: mm # Gravatar style
  guest_info: nick,mail,link # Custom comment header
  pageSize: 10 # Pagination size
  language: # Language, available values: en, zh-cn
  visitor: false # Article reading statistic
  comment_count: false # If false, comment count will only be displayed in post page, not in home page
  recordIP: false # Whether to record the commenter IP
  serverURLs: # When the custom domain name is enabled, fill it in here (it will be detected automatically by default, no need to fill in)
  #post_meta_order: 0

Although there is custom_file that is the #postMeta: source/_data/post-meta.swig,
I don't know how to use it.
I only can use code below to realize hide it...
(我不知道source/_data/post-meta.swig文件怎么用，我只能通过下面的代码去隐藏它)

.post-meta span:nth-child(3) {
  color: transparent;
  background: transparent;
}

However, it not only waste a little bit performance, but also the update time spanand create time span cann't be centered.
(不仅浪费了一点性能，发表时间和更新时间两个span还不能居中)

Other Information

I hope to add an option for it or give me some better ways to solve it.
It looks a bit redundant and Cumbersome to me.
Thanks!
(我希望增加一个选项或者能给我一些更好的方法去解决这个问题，它对我而言看起来有点多余且繁琐，谢谢!)
