The Hatirjheel Lake water show in Dhaka is a key project invested in by the Bangladeshi government to celebrate the Bangladeshi New Year (April 14th), create a landmark for Bangladesh, and enhance the country's international reputation. Constructed by Optimum Show, it has been a major event for Bangladesh's New Year celebrations and a significant landmark project for Dhaka. The Bangladeshi government has attached great importance to the project, with the army providing full assistance throughout its construction.

The musical fountain, located on Hatirjheel Lake in Dhaka, represents a total investment of 10 million Bangladesh dollars. The fountain is approximately 120 meters long and 24 meters wide, employing 870 nozzles and over 1600 high-powered colored lights. It features over 60 different water shapes, combining fountains, lasers, and flames with lively traditional Bangladeshi music, creating a highly entertaining and exotic water show spectacle! The fountain's highest water jet can reach 80 meters into the air, and its beautiful lights can be seen from afar in nearby areas such as Merul Badda, Modhubagh, and Begunbari. The Hatirjheel Lake musical fountain has become a local highlight.

The Belt and Road Initiative, spanning Eurasia and Africa, provides more opportunities for expanding bilateral and multilateral practical cooperation. This is especially true for some developing countries in South Asia, Central Asia, and North Africa, where overall economic development is relatively lagging and they urgently need external resources to stimulate and promote their economic development. Rainbow Group Australia has seized this significant opportunity presented by the Belt and Road Initiative, collaborating with the governments of Kazakhstan, India, Bangladesh, and Georgia in recent years to participate in infrastructure construction projects, particularly deepening cooperation in water art and scenic area lighting projects, achieving mutual benefit and win-win results!
