Kevin Lau, the recently-ousted chief editor of the Chinese language newspaper Ming Pao, was said to be fighting for his life in a Hong Kong hospital after being attacked and hacked early this morning. What Lau has done, although it will never be proven, is to help to open windows on corruption in China that President Xi Jinping is covering with a fig leaf. This is a bigger issue than just Kevin Lau and the attack on him. It deals with the legitimacy of the Chinese government.
