Context: The Bank of East Asia Limited () often abbreviated to BEA (), is the largest independent local bank and the third largest bank in Hong Kong.  Its chairman and chief executive is Sir David Li.  Its head office is in Central. HSBC (), officially known as The Hongkong and Shanghai Banking Corporation Limited (), is a wholly owned subsidiary of HSBC, the largest bank in Hong Kong, and operates branches and offices throughout the Asia Pacific region, and in other countries around the world.  It is also one of the three commercial banks licensed by the Hong Kong Monetary Authority to issue banknotes for the Hong Kong dollar. Michael Graham Ruddock Sandberg, Baron Sandberg, CBE (, 31 May 1927 – 2 July 2017) was executive chairman of The Hongkong and Shanghai Banking Corporation from 1977 to 1986. Overseas Trust Bank Limited (OTB) () was a bank in Hong Kong.  It was established in 1955 by Chang Ming Thien, a Malaysian businessman and it was listed on the Hong Kong Stock Exchange in 1972.  It was the fourth largest bank in Hong Kong before acquisition. Joseph YAM Chi-kwong, GBM, GBS, CBE, JP (任志剛; born 1948, Hong Kong) is a Hong Kong statistician, economist and civil servant.  He was the first Chief Executive of the Hong Kong Monetary Authority, Hong Kong's "de facto" central bank, holding the position for 16 years.  Since 2011, Yam has been a member of the board of directors of the Swiss Bank UBS AG.  In 2014, following UBS AG's restructuring, he was appointed to the board of directors of the UBS Group AG.  He has been a non-official member of the Executive Council of Hong Kong since 2017. Emilio Botín-Sanz de Sautuola y García de los Ríos (1 October 1934 – 10 September 2014) was a Spanish banker.  He was the executive chairman of Spain's Grupo Santander.  In 1993 his bank absorbed Banco Español de Crédito (Banesto), and in 1999 it merged with Banco Central Hispano creating Banco Santander Central Hispano (BSCH), which became Spain's largest bank, of which he was co-president with Central Hispano's José María Amusategui, until Amusategui retired in 2002.  In 2004, BSCH acquired the British bank Abbey National, making BSCH the second largest bank in Europe by market capitalisation.  He was known for his obsession with growth and performance as well as regularly visiting branches. Industrial and Commercial Bank of China (Canada), formerly The Bank of East Asia (Canada), was founded in 1991; it was the Canadian unit of the Bank of East Asia Group (BEA) in Hong Kong.  The bank operates five branches in Canada and offers retail banking products catering to expatriate Hong Kong Chinese in Canada.  The bank operated at Hong Kong Chinese themed malls or areas with large Hong Kong Chinese population.  A 70% stake of the bank was sold by former parent Bank of East Asia in January 2010 to Industrial and Commercial Bank of China and on July 2 the bank changed its name to the current name.  BEA retains a 30% stake as BEA focuses business in Hong Kong.  Signage at all Canadian branches were changed to reflect the new ownership.  BEA Canada is the second Hong Kong based bank to pull its Canadian operations.  Standard Chartered Bank (Hong Kong) sold its Canadian branches and operations to Bank of Montreal and Scotiabank respectively in the 1990s. The right of abode in Hong Kong is the right to legally reside in Hong Kong without any limit or condition of stay being imposed by the Hong Kong Immigration Department.  As the People's Republic of China stood to resume sovereignty over Hong Kong from the United Kingdom, the nationality of Hong Kong people as well as their right of abode in the territory was formalised prior to the 1997 handover.  Since Hong Kong has never been an independent country, there is no provision for its own citizenship status.  Hong Kong Permanent Resident is the legal status for those who have the right of abode in Hong Kong, which is the "de-facto" citizenship status in Hong Kong.  Most citizen rights in Hong Kong (such as the right to vote) are granted to all permanent residents, while some (such as the right to hold a HKSAR passport, or becoming a high-rank public officer such as the Chief Executive) are restricted to permanent residents who are also Chinese citizens. 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.
