时隔半个世纪，人们仍能听到１９５２年２月１０日从河北省原省会保定城东关大校场传来的那两声沉闷的枪响。这是传播最远的枪声。全保定市听到了，全河北省听到了，全中国都听到了。这是传播最久的枪声。它穿过５０年代时间的帷幕，穿过２０世纪的时空，在２１世纪听来还是那? Half a century later, people still could hear the dull gunfire that came from Dong Guan University, Baoding City, the capital of Hebei Province, on February 10, 1952. This is the farthest gunshot spread. All heard of the whole city of Baoding, all heard in Hebei Province, all of China have heard. This is the longest gunfire. It crosses the curtain of the 1950s through the twentieth-century space-time, in the 21st century it still sounds?
