Tour Guides' Protestation in Guilin

I just know that all the Guilin tour guides had a protestation in front of the Guilin government and also in Guilin city center in late July.
I was not in Guilin then so I don't know much about it. It says a journalist from Guilin Daily Newspaper which is run by the government exposed the original prices of all the tourism industry. What the journalist did makes it difficult for tour guides to make living. Thus, all the tour guides here went to protest hoping the government could help them. Unluckily, just like the other big protestations in China the government sent the army and policeman to force protestors away.
