A nine-day cross-strait book exhibition was launched in Macao on Saturday, displaying some 200,000 books provided by publishing houses from the Chinese mainland and China's Taiwan, Hong Kong and Macao regions.

The host Macao Publishers' Association said in a press release that the books on show cover a wide range of content including literature, history, philosophy, art, politics, leisure, facility, sports and religion.

The exhibition set up a special section for books on the 2008 Beijing Olympics.

A dozen of writers from the Chinese mainland, Taiwan, Hong Kong and Macao scratched signatures for the readers at the conclusion of the opening ceremony.

The book show has been an annual traditional cultural event for some 20 years.
