Partial quote:
"Certainly North Korea no longer merits much respect among ordinary Chinese, who have taken to insulting Kim Jong-un as "Fatty Kim" or "Fatty the Third", in reference to his father and grandfather, on the Chinese internet."

If you think the free world has been critical of Kim Jong Un, the Chinese people must be pretty fed up with North Korea too to be this disrespectful to Kim Jong Un now during these times.
