围观 (wéiguān): surround and watch
“Cruel, inhumane surrounding and watching of the 楼主 lóuzhǔ.”
An invocation to crowds to gather around someone or something, online or in the real world, and observe. It implies that an occurrence is receiving public scrutiny. The 2010 Southern Weekend
article “Scrutiny is Power: How ‘Surrounding and Watching’ Has Changed China” (关注就是力量--围观改变中国
) popularized this sense of the term. Xiao Shu writes, “What’s important was that public scrutiny was effective. They could no longer view it as being immaterial—they had to respond to the public scrutiny” (重要的是，围观起作用了，他们不能再视围观为无物，他们必须回应围观).
