On August 24, 1966, during the so-called Great Cultural Revolution, my home was ransacked by the "young generals" who called themselves the Red Guards. All my personal belongings, clothes, and books were taken; nothing remained behind after the sweep. Furthermore, I was forced to move from the rooms in the northern wing of the building and to make my abode in the small cottage in the southern part. At the time I was quite upset, but soon I learned to put the matter aside and make nothing of it. In that period of "leisure," I was able to write the following essays in draft form. Since I didn't have a single book for reference, the writing was entirely from memory. By September 6 I had completed the first essay, and subsequently, on November 10, the second was produced. As for the third, I can no longer recall the date of its completion.
