On the date of the 23rd anniversary of end of the Tiananmen Square protests, the Shanghai Composite Index fell 64.89 points.
Written in the American style, the date of Tiananmen Square was 6/4/89.
The WSJ also notes that the days opening was 2,346.98, which seems to refer to 23, and the date reversed.
Predictably, of course, searches for Shanghai Composite Index were banned on Weibo within hours.
