The following list describes booklets which were banned in the 1960s in Hong Kong and Taiwan because of dealing with sexual topics. They were available only under the counter, did not enter libraries and official bibliographies and usually do not provide exact metadata. Most names are pseudonyms and the data on the place and year of publication are mostly missing. The Sinologist Wolfram Eberhard, who had dealt with similar subjects in his Guilt and Sin in Traditional China (Berkeley 1967) and The Daily Life of a Chinese Courtesan Climbing up a Tricky Ladder (Hong Kong 1980), possibly planned on also dealing with this popular material which he collected on his travels but he never found the time. Therefore, it is to be considered serendipitous that this little collection was acquired by the Bavarian State Library in Munich, probably the only library in the world to hold it.
