A much better link would be something that talks about this close. For instance https://www.cbc.ca/news/business/chinese-yuan-falls-to-11-ye...
I'm still confused by the coverage, since it's trading at 7 CNY to 1 USD. That's still higher than the 52 week low. Also it's higher on the chart on the right which shows the 5 year closes. I'm very confused, since coverage doesn't jive with either chart.
