Chinese investors vent anger on microblogging site Weibo

Stock markets in London, Paris and Frankfurt have fallen sharply as fears of a Chinese economic slowdown continue to haunt investors.

China's central bank devalued the country's currency, the yuan, two weeks ago, raising fresh concerns that a slowdown in the country's economy was worse than originally feared.

The BBC's Celia Hatton says Chinese investors are angry at the collapse of their investments and want more state intervention.

That is something the Chinese government is trying to do less of.
