　　1）。 Search the relevant keywords, title and URL of the original site, and these contents will be replaced with the site information promoted by hackers in the search results, Website promotion However, the ranking of the original site will continue for a period of time.  
　　2）。 The title and URL of the original site have not been replaced, but they will jump to another site. In this case, the main reason is that Baidu snapshot has not been updated. This is an earlier discovery time. Please repair the code as soon as possible.
