Observe the above 5x5 matrix of Chinese characters: when read horizontally, it consists of five lines from five different poems, and so does it when read vertically, of the exact same lines. I call it the magic square of Chinese poems. With a brute-force-search over 287,000 lines from the Complete Collection of Tang Dynasty Poems, I discovered 2 such sets. You can reproduce my results by running "gcc -O3 mgsq5.c; ./a.out".
