Tell me my understanding: this sentence means that you use a blog (or other) to import the collected links into this blog for filtering. Simply put, it is to point to this blog, because the collected domain name is weighted, but because it is not done, Baidu will judge it as an invalid connection if it can't catch something, so you must first turn it into a valid connection, and then this blog (or blog) becomes a weighted blog.

Personal opinion: This method doesn't seem to cheat, but you should know that when links are imported to a site, because the previous links have been weighted in Baidu, a large number of inconsistent links will be imported into the blog, and Baidu will also judge them as inconsistent or spam links. Once it is discovered, let alone the weight, the ranking is estimated to be gone.

The above is just my personal opinion, and my ability is limited. Please don't spray.
