Various publications, in English and in Chinese exist;
the original Chinese source material is generally no longer available accept as precious archival material held by Organizations
or privately; some of these have been edited and reissued from HK and PRC book companies.
Some of the earlier HK publications have been scanned and made partially
available on some internet websites; with some changes in chapter content. The original Chinese text does not always accompany
them. Even if the Chinese text was made available, newer publicaitons and reissued ones,
are almost always now in Pinyin Simplified Chinese...which
results in loss
of translation content.
