Mr Bin was eventually released by police and had his computers confiscated but was allowed to keep his mobile.
Mr Bin posted another video to Twitter where he confessed he was still afraid he may get arrested again and that all Chinese people needed to stand together.
"I have been saying that my safety relies on everyone. It's useless to be fearful. It's useless to beg them. The more you fear, the more they do things this way. The only way out is that everyone stand up," he said.
The coronavirus has been spreading panic across the globe as the latest death toll from the virus rises to 304 in China.
The World Health Organisation expected that number to rise significantly and a recent study suggested that as many as 75,815 people could be infected in Wuhan.
