The Chinese typewriter in fact is a mechanical setup of thousands in Chinese characters in lead, placed in a logical format of A2 size. This was a mechanical version of the type-setting of Chinese print-shops. It was being used from 1960s to early 1980s when Chinese typing was being replaced by computer. There are about 2500 words on the plate and 3600 spare words. FEBC Hong Kong did not use a typewriter for radio scripts because it was time consuming. They used it for official documents and correspondence. Chinese churches used to type their Sunday service bulletins and in-house publications. See also #F01407.
