A modern lightweight mouse-over pop-up dictionary for Chinese! After you install this extension, you have to reload the page(s) you want to use it on and enable it by pressing the extension's button first! This is only necessary after installing the first time or if the extension has updated. LiuChan (liúchàng) is an extension for chrome that allows you to mouse-over Chinese to instantly look up the dictionary. 流畅 (liúchàng) stands for fluency in a language. It started out as a port of RikaiChan (and its Rikai derivatives) and has since grown into an extension that holds its own with new features and improved performance.
