• The Mandarin name “樟宜” is the transliteration of the English name “Changi”.
• The name “Changi” appeared as early as 1828, in the “Plan of the British Settlement of Singapore” published that year. Elsewhere, the name was also written as “Changhi” or “Changei”.
• There are several different explanations for the origins of the name “Changi”. Henry Ridley, the first director of the Singapore Botanic Gardens, believed that “Changi” was derived from the Chengal or Chengai tree (Neobalanocarpus heimii, also known as Balanscorpus heimii or Balano scorpas). Another belief is that the name was derived from the climbing shrubs known in Malay as changi ular (Apama corymbosa) that grew in the area.

The local aquaculture operator is using a patented technique of pumping seawater through an ozone sterilisation filter to build an enclosed floating fish farm off the coast of Changi. The farm is expected to produce 20 times the yield of a conventional fish farm while improving energy and labour efficiency. (Lianhe Zaobao, 20/11/2019)

• Prominent landmarks in Changi include Changi International Airport, Changi Prison, Changi Village, Changi Hospital, and Changi City Point. Changi is also a popular recreational area.
• In 2002, a 150-year-old Chengal Pasir tree (Hopea sangal) in Changi, believed to be the last of its species in Singapore, was cut down illegally by a property management company, triggering public concern. Fortunately, seeds from the tree had been collected and passed to the National Parks Board, who subsequently planted them around Singapore.
