This kind of 'Charm' is designed to be hanged in the centre of the cross-beams comprising doorways. The idea is that everyone who traverses through this space (doorways are 'rounded' within traditional Chinese doorways - a disgin retained in the film the 'Hobbit' and other related Movies) are 'blessed' by the contained spiritual message!
