It turns out that the Internet has a little bit more information about this affair than I thought, specifically a 2005 report about the Chinese Gold Bar Ciphers (in Chinese, and possibly copied from an earlier blog entry), which seems to paint a rather more complicated story.
(Incidentally, a commenter on Klaus Schmeh’s website (where the Chinese Gold Bar Cipher is #19 of his top 25 ciphers) Google-Translated parts of this page into rather wonky German (the commenter preferred to stick with Google rather than ask someone at a nearby Chinese restaurant), but it’s probably not the best translation you’ll ever see).
The Big Fat Secret History – and I think you’re going to like this – seems to be that at the Shanghai branch of Citibank on 3rd March 1933, General Wang Jialie allegedly bought 300 million of Citibank’s shares for just over $300 million, but that (inevitably) everyone involved has somehow managed to cover up this transaction ever since. Believe it or don’t (as is your right): but that is apparently what it says.
(Note that in 1933, it wasn’t yet “Citibank” but was still “National City Bank”: according to Schwikipedia, its Shanghai branch was opened in 1902 by the International Banking Corporation, which in 1918 then became a subsidiary of National City Bank. NCB seems to have been a very major contributor to the 1929 Stock Market Crash: its boss at that time, Charles E. Mitchell, resigned in 1933, following investigation by the Pecora Commission. Hence 1933 was both the bottom of the stock market and an interesting time in the NCB’s history.)
Anyway, one of the gold bars is claimed to be a licence attesting to this transaction and its witnesses: (Kuomintang Generals) [He] Yingqin, Zhu Peide, Li Fulin; as well as Governor Sijie, Ruanruo Fu, and secretary Anna Si Lina.
“王家烈将军于中华民国 1933 年 3 月 3 日 10 时 30 分 3 秒（ 股票以秒计算 ），以黄金、珠宝、法郎、马克、英磅折美元叁亿伍仟伍佰万元。存入美利坚合众国美国花旗银行上海分行。鉴存人何应钦、朱培德、李福林等（ 当时都是军长 ）三人座谈入行。行长斯杰、阮若夫，秘书安娜斯丽娜，金货总重壹点捌公斤”
Zhu Peide was a Military Intelligence man who had worked his way up to become a general: here’s a photo of Chiang Kaishek crying at Zhu Peide’s 1937 funeral. Li Fulin was also a General – there’s a (roughly-translated) biography of him here (e.g. it says he died of hypertension aged 79 in Hong Kong in 1952). And He Yingqin was also a General: there’s a picture of him as he accepts the Japanese Instrument of Surrender in 1945.
However, “Governor Sijie, Ruanruo Fu, and secretary Anna Si Lina” I don’t (yet) know anything about.
The same page also reproduces three American Chinese-language newspaper articles from 1993, which I’m guessing are all saying much the same thing (but please feel free to correct me on this).
