@kkbt 我有些在搜索引擎搜到的要登陆。知乎曾经有段时间全部都要登陆才可见（我前几年长时间的、频繁的发知乎的回答给现实认识的人讲话，见过知乎从非登陆可看→全部都要登录才能看→非登陆可看的样子）
Why is this step necessary? hello.2heng.xin might not be the server where you are registered, so we need to redirect you to your home server first. Don't have an account? You can sign up here
hello.2heng.xin
