After Temu is added to the library, the time it takes to join a site depends on the update frequency and review process of each site. Some sites may be automatically updated within a few hours, while other sites may take days or weeks to review and add new content.

In addition, Temu's content may also be excluded from certain sites because their themes or content do not meet the requirements of the site. In general, the time difference between Temu's entry into the library and site publishing is based on various factors, including the site's review speed and rules, and how well Temu's content matches the site's requirements.
