Three Unknown Chinese Codebooks (ca. 1905)

I came across a reference to three Chinese codebooks used around 1905: 「密電秘鑰」（Midian Miyao）、「中国密電簡明表」（Zhongguo Mi dian Jianming Biao）、「行軍電報」（Xingjun Dianbao）. Their format seems to be similar to that of known codebooks. I added a note on this in "中国の暗号：1871-1945" and its abridged version in English: "Chinese Cryptography: 1871-1945".
