DuEm6: There are reuploads of the programs on youtube, youku, bilibili, etc. There are also places to stream the TV channel. Google suggests http://www.zhiboba.org/pindao/tianyuanweiqi.html and https://epg.sports8.cc/huikan/381/. But I couldn't make them work. Perhaps because I'm not in China. Perhaps because I don't know Chinese and misunderstood the websites.
