What is the fine-grained topic of the following text: Amid the great expectations of the West Kowloon Cultural District;the opening of new public creative spaces at restored historic buildings like PMQ and Central Police Station; the buoyant art market created by headline-grabbing auctions and art fairs as well as the opening of galleries, arts and culture are beginning to take centre stage in a city once derided as “cultural desert”. Only return the topic.
The growth and development of arts and culture in West Kowloon and the transformation of the city from a "cultural desert".
