Didatuan.com, which went online in July 2010 as a group-buying website and once had a top-five trading volume, closed its group-buying business on March 31 and turned to develop a group-buying navigation service, according to information posted on tuan800.com on April 3.

At the moment, however, didatuan.com cannot be accessed online.
