Shanghai party newspaper, Jiefang Daily published a letter from Li Zongxin (in Chinese here), translated by Joel Martinsen, via Press Interpreter:
Jiefang Daily Editorial Office: I am a common citizen living on Loushanguan road, and a loyal reader of your newspaper. I am writing today because I wish to tell you editors a few heartfelt words.
On April 16th, some people in Shanghai conducted a parade demonstration concerning Japan. The marchers passed by the entrance to our community. At first, we were curious about this parade. We felt that this was a protest against unfriendly attitudes and actions of Japanese rightists, and that it expressed a fervent patriotism. But later on what I saw with my own eyes distressed me somewhat. I saw Japanese restaurants smashed, with shattered glass covering the ground. I had not expected actions of this kind, and I was deeply upset.
