Tomorrow is a red letter day for the city's bookworms with the opening of this year's Hong Kong Book Fair at the Convention and Exhibition Centre. A multitude of titles will be presented by 480 publishers in 13 themed halls. The number of exhibitors is up 1.5 per cent from last year, and includes representatives from 21 countries, including Argentina, Belgium, Denmark, India, Japan, Malaysia and Thailand. With the growing interest in Spain's culture, this year's event also features a Spanish pavilion, showcasing six different publishers. According to the Spanish Cultural Association of Hong Kong, Spanish classes have become increasingly popular over the past six years, with students as young as three years old attending. Other highlights include the Greenpeace Promotion on Thursday, the British Cultural Day on Friday and Children's Day on Saturday. The Greenpeace event features a booth where visitors can learn to pack books in a more eco-friendly way. Readers will get a chance to fire questions at Peter Stuart, Polly Dunbar, Chip Tsao and May Chan Mee-fung, acting as 'living books', during the cultural day organised by the British Council. The Children's Day will showcase English storytelling. Running until July 29, the fair will also host a number of seminars for young readers, including a series of talks on new Japan media by Japanese critic Liu Li-er and writer Lily Franky. Other interesting topics include the crossover between eastern and western culture. And next month's Beijing Games will be celebrated in the Olympic Zone. For those who can't get enough of books and literature during daylight hours, opening hours are extended till midnight on Friday and Saturday. On these two days, bus services have been arranged for readers from 10pm to 1.30am, while ferry services between Wan Chai and Tsim Sha Tsui will be more frequent after 8pm. Ticket prices for the event are HK$25 for adults and HK$10 for children, with free admission for children under three and adults over 65.
