Question: When was the Chinese city producing All About Ah-Long taken by the British?

full_context: Document 1: British Empire: By the start of the 20th century, Germany and the United States challenged Britain's economic lead. Subsequent military and economic tensions between Britain and Germany were major causes of the First World War, during which Britain relied heavily upon its empire. The conflict placed enormous strain on the military, financial and manpower resources of Britain. Although the British Empire achieved its largest territorial extent immediately after World War I, Britain was no longer the world's pre-eminent industrial or military power. In the Second World War, Britain's colonies in South-East Asia were occupied by Imperial Japan. Despite the final victory of Britain and its allies, the damage to British prestige helped to accelerate the decline of the empire. India, Britain's most valuable and populous possession, achieved independence as part of a larger decolonisation movement in which Britain granted independence to most territories of the Empire. The transfer of Hong Kong to China in 1997 marked for many the end of the British Empire. Fourteen overseas territories remain under British sovereignty. After independence, many former British colonies joined the Commonwealth of Nations, a free association of independent states. The United Kingdom is now one of 16 Commonwealth nations, a grouping known informally as the Commonwealth realms, that share one monarch—Queen Elizabeth II.

Although Hong Kong Island and Kowloon were ceded to Britain in perpetuity, the New Territories -- which comprised over 90 per cent of Hong Kong's land -- had such a vital role in the economy that the British government agreed to transfer sovereignty of the entirety of Hong Kong to China upon the expiration of the lease in 1997.

Document 14: British Empire: In September 1982, Prime minister Margaret Thatcher travelled to Beijing to negotiate with the Chinese government on the future of Britain's last major and most populous overseas territory, Hong Kong. Under the terms of the 1842 Treaty of Nanking, Hong Kong Island itself had been ceded to Britain in perpetuity, but the vast majority of the colony was constituted by the New Territories, which had been acquired under a 99-year lease in 1898, due to expire in 1997. Thatcher, seeing parallels with the Falkland Islands, initially wished to hold Hong Kong and proposed British administration with Chinese sovereignty, though this was rejected by China. A deal was reached in 1984—under the terms of the Sino-British Joint Declaration, Hong Kong would become a special administrative region of the People's Republic of China, maintaining its way of life for at least 50 years.
