Context paragraphs:
New Territories: New Territories () is one of the three main regions of Hong Kong, alongside Hong Kong Island and the Kowloon Peninsula.  It makes up 86.2% of Hong Kong's territory, and contains around half of the population of Hong Kong.  Historically, it is the region described in The Convention for the Extension of Hong Kong Territory.  According to that the territories comprise the mainland area north of the Boundary Street of Kowloon Peninsula and south of the Sham Chun River which is the border between Hong Kong and Mainland China, as well as over 200 outlying Islands including Lantau Island, Lamma Island, Cheung Chau, and Peng Chau in the territory of Hong Kong.

Taishanese people in Hong Kong: Sze Yap Cantonese (Chinese: 四邑廣東人; Taishanese: Sli Yip Gong Ong Ngin; Cantonese: Sei Yap Gwong Dong Yan; Mandarin: Si Yi Guang Dong Ren) represents the second largest Han group in Hong Kong after the group of people originating from the Guangzhou-Sam Yap region.  The Sze Yap Cantonese comes from a region in Guangdong in China called Sze Yap (四邑), now called Ng Yap, which consists of the cities of Taishan, Kaiping, Xinhui, Enping, Heshan and Jiangmen.  The Sze Yap Cantonese group have contributed much to what makes Hong Kong a success.  In the 1960s, Hong Kong people of Sze Yap origin represented about 30% of Hong Kong's total population and today this population still increases as more immigrants from the Taishanese speaking areas of Guangdong in mainland China continue to immigrate to Hong Kong.

The Back Door (fiction): The Back Door was an anonymous work of invasion literature serialised in Hong Kong newspaper "The China Mail" from 30 September through 8 October 1897.  The work, written in the form of a historical account, describes an imagined Russian and French landing at Hong Kong's Deep Water Bay, followed by shelling of Victoria Peak, a sea battle in the Sulphur Channel between Hong Kong Island and Green Island, and a last stand at Stonecutters Island in which British forces were decisively defeated.  The story was intended as a criticism of the lack of British funding for the defence of Hong Kong; fears of invasion were driven by French expansionism in Southeast Asia and increasing Russian influence in Manchuria.  It was speculated, but never proven, that members of the Imperial Japanese Army read the book in preparation for the 1941 Battle of Hong Kong, in which Japanese forces overran Hong Kong (via the New Territories, rather than Hong Kong Island) in just 18 days.  In terms of its style, it follows the model laid out by George Tomkyns Chesney's "The Battle of Dorking", but is noteworthy for its attention to detail, even giving real names of individual soldiers and ships; one reviewer described it as "unique" in its verisimilitude, stating that only William Le Queux's "The Invasion of 1910" and Cleveland Moffett's "" could compare to it.

Westernisation in Hong Kong: After the First Opium War in 1842, China ceded Hong Kong Island to Britain under the Nanking Treaty.  Subsequently in 1898, China leased the lands surrounding Hong Kong Island which includes the New Territories, the Kowloon peninsula and outlying islands to Britain rent free for 99 years under the Convention for the Extension of Hong Kong Territory following China's defeat in the First Sino Japanese War.  These unequal treaties has granted Britain the power to colonise the whole of Hong Kong.  Even though Hong Kong was eventually handed back to China at the handover in 1997, the British culture has remained evident in Hong Kong's way of life in various aspects after more than 150 years of British rule.  In several major aspects such as the education system, language and food culture, the British culture has been so ingrained during the colonial rule that it has become an integral part of Hong Kong culture.

Hong Kong Morris: The Hong Kong Morris (, Cantonese pronunciation: "Heung Gong Gwoo Doi Ying Gwok Mo Tuen", literally Hong Kong Ancient English Dance Platoon) is an English morris dancing team or side founded in Hong Kong in 1974.  The side now has two chapters, the Hong Kong Morris in Hong Kong and the Hong Kong (UK) Morris, colloquially known as The Brackets, in the United Kingdom.  In its heyday, in the late 1980s and early 1990s, the Hong Kong Morris was one of the largest Cotswold morris sides in the world.  The side is committed to the principles of multiculturalism and inclusivity, and has always encouraged a multicultural membership and mixed dancing.  The return of the former British colony of Hong Kong to China in 1997 has had no effect on the side's activities, and it continues to flourish as a notable example of the resilience of Western cultural activity in postcolonial Hong Kong.
