political VIPs and senior leaders of various countries during the World Expo; play the
promotional video of the World Expo Shanghai 2010, and some choice images or video clips
cut from Shanghai World Expo; and play extra-large wall surface World Expo 365-day countdown
board (6,030 m2). Moreover, the extra-large wall surface World Expo LOGO in the Bund can be
seen from Xujiahui high-rise buildings, the Cloud Nine Plaza in the Zhongshan Park, and Lupu Bridge, etc. The LED
display can also be utilized to play the promotional video of scenic
spots in Binjiang and the Bund, and various types of promotion and introduction videos of the
World Expo, and to attract more people to stop and watch, which can better promote brand
awareness, social influence and brand effect of enterprises, serving as an ideal platform
for enterprises to explore Shanghai market and to launch advertising campaign. (Please see
