References here yesterday to Epiphany 
and to Chinese logic suggest two observations—

First, a political interpretation of the number "64.89" 
from Monday's Shanghai stock market index
yielded the date  6/4 in 1989—

Second, an interpretation of 64.89 as the number  64 in 1989
(on the Feast of the Epiphany, January 6)—

Note of January 6, 1989 showing 
the 64 hexagrams in the von Franz style

No connection of the number  64 with the date  6/4 is implied.
