[Q]: Article: Ocean Park Hong Kong is a theme park in the Southern District of Hong Kong Island. The park was built with donations from the Royal Hong Kong Jockey Club (now Hong Kong Jockey Club) and opened on 10 January 1977. Today it offers affordable marine animal education and entertainment and is a private organization for commercial purpose. In the early operation of the park, the main sources of income for the park were the ticket prices and the funding from the Jockey Club. Since the ticket price was low, most of the time Ocean Park was operating under deficit . In July 1987, the government established a 200 million trust from the funding of Jockey Club, under the Ocean Park Corporation Ordinance. This separated Ocean Park from Jockey Club and became a non-profit organization; it needs to be responsible for its own income and was allowed to use commercial means to operate the park. Since it was permitted to use commercial means to operate, it gradually raised its ticket price and the deficit turned into profit. In 1992, 3 million visitors visited the park. Since 1998, the East Asian financial crisis , aging attractions, and the passing away of the killer whale, the park recorded a deficit for a couple years. Although it was allowed to host 2 pandas in 1999, the number of visitors did not go up and Ocean Park was forced to close its water attractions and the "Old Village" attraction and turned to bring in more rides in an attempt to capture the youth demand. Together with the opening up of mainland visitors under the Individual Visit Scheme, Ocean Park recorded an astonishing 4 million visitors in the year 2004-2005, the highest since the park opened. In March 2005, Ocean Park made its redevelopment plan. On 23 November 2006, Ocean Park held a groundbreaking ceremony for its redevelopment.
