Either this is an elaborate hoax (I doubt it) or an educated person with a decent command of the English language (educated in the West at some point probably) is imprisoned (for political/religious reasons) in the great Chinese Gulag Archipelago of factories through out the workers paradise of Communist China. Remember folks, it is still a Communist led country where dissent is not tolerated, much less anything else. The fact that they’re practicing consumerism (the heart of communism, really, given a spiritual purpose in life is non-existent except for those who attempt to practice Falungong) makes sense eventually. Less rioting, more control and well, happy workers, just what every dictator appreciates and will pay any price to achieve. Pray for them and their eventual freedom. Merry Christmas.
The letter appears to have been written on a project planning pad of some sort (note printed space at the bottom to insert the page number and date), and appears to have been written with a fountain pen.
