After upgrading the network to fiber one, I need to fully utilize its bandwidth to make sure that each penny I spent is worthwhile. How to do so? Try bt. One of the best torrent site for Chinese should be btchina. No need to login; you can search the the results form multiple forums. However, it does not support firefox browser, which is my defaul browser on ubuntu. Based on the fact of firefox's tremendous popularity, it's not hard to find a workaround for it. Here it is: Show btChina userscript for greasemonkey extension.
It not only shows the results correctly for you, but also removes the annoying ad window in the middle of the screen.
