Overview: Just a few years ago, Hong Kong was well-known as the location of many bookstores specializing in so-called "banned books" that were forbidden for sale in mainland China. However recently, they have nearly disappeared from the market, with many of the bookstores that carried them closing shop. This steady movement is strongly linked to the change in political leadership in mainland China, which has placed greater pressure on merchants to comply with the political view of the mainland. In this episode, we follow the traces of Hong Kong's political freedom amidst a rapidly changing era.
