 During the 2005 East Asian Games in Macau, a competition was held to determine the logo for the 5th East Asian Games. On 11 July 2005 a fireworks emblem, designed by Clement Yick Tat-wa, was selected. The design makes reference to the five Olympic rings, and the sparkling fireworks symbolise the energy of athletes striving to fulfill their potential and to achieve sporting excellence.
 A slogan contest was held at the Asian Games in 2006 and the winning suggestion was "Be the Legend" (Chinese: 創造傳奇一刻; Jyutping: cong3 zou6 cyun4 kei4 jat1 hak1); fitting well with the ideals of athletes reaching their potential and achieving legendary victories. This slogan was submitted by secondary school student Choi Sau-chu (蔡秀珠). The event song is You are the Legend (Chinese: 衝出世界; Jyutping: cung1 ceot1 sai3 gaai3).
 "Dony" (Chinese: 東仔; Jyutping: dung1 zai2) and "Ami" (Chinese: 亞妹; Jyutping: ngaa3 mui6), carrying the motifs of a flaming torch and the Lion Rock, were the mascots of the Games.
 A set of "Heartwarming Stamps" were released in March and another set was available in August while commemorative stamps were issued on the opening day of the event, 5 December.
 The 1 year countdown to the 2009 East Asian games began with Hong Kong Chief executive Donald Tsang inaugurating a special countdown clock in Hong Kong Cultural Centre on 5 December 2008. The ceremony was also attended by chairman of the East Asian Games planning committee Timothy Fok and heads of delegations of the nine countries. The countdown clock is based on the Mascot "Dony". The Cantonese version of the theme song You are the Legend was also performed for the first time by 30 Hong Kong singers including Alan Tam. Representatives of the Hong Kong 18 district councils were also present. For the 300-day countdown, 24 athletes were invited to sing the theme song at the Alan Tam Hacken Lee concert.
 A flower show was opened to the public on 13 May at Victoria Park. The show lasted 10 days featuring 60,000 pots of themed flower. Around 200 organizations from 20 countries participated in the show. The new Tseung Kwan O Sports Ground was opened on 19 May to celebrate the 200 days count down. A relay race was held between the HK police, HK immigration department, Leisure and Cultural department, HK Fire service, Customs and Exercise department, Hong Kong University of Science and Technology and Sai Kung District sports association. There was a dragon and lion dance performance and a tree planting ceremony. A cheerleading competition was also held.
 A torch relay was held on August 29 as part of the 100-day Countdown. The relay held the theme "Light the way to the EAG". The torch is a curvy cylinder with a square top and round bottom. It resembles the horn of an ox as 2009 is the year of the Ox. They create the patterns of "Lucky Clouds" to put forward the concept of yin and yang. This also convey the message that Hong Kong is a place where the Chinese and Western cultures meet.
