If someone shares a Weibo short link starting with t.cn, but you prefer not to click on it to avoid being tracked by Weibo, you can use this tool to reveal the actual destination URL that the Weibo short link redirects to. This tool uses our server to access the t.cn Weibo short link on your behalf and automatically follows multiple redirects to find the underlying real link. It also attempts to clean up some basic tracking link parameters using simple rules.
