The Chinese white dolphin, due to its scarce population, is also known as the "panda of the sea". It was the "mascot" for the return of Hong Kong to China in 1997. It is the only first-class national key protected aquatic wild animal in the dolphin family in China. There is currently the largest Chinese white dolphin population in terms of resources in the Pearl River Estuary. The population generations are relatively complete, and it is the habitat with the largest number of Chinese white dolphins in China.

The Management Base of the Chinese White Dolphin Nature Reserve in the Pearl River Estuary is located in Zhuhai City. The construction of the base integrates functions such as protection, research, rescue, domestication, popular science education, publicity and education, sightseeing, and eco-tourism. It strictly implements relevant national laws, regulations, guidelines, and policies regarding nature reserves, formulates the overall plan and various management systems of the nature reserve, and organizes and conducts publicity and education on nature conservation.  

In order to better interpret, explain and publicize the work, and to carry forward the purpose of everyone taking action to protect the "pandas of the sea", the Science Popularization Museum of the National Nature Reserve Administration of Chinese White Dolphins, which combines multimedia and marine ecology, has been completed. Diheng is honored to serve as the equipment supplier of multimedia projection for this Science Popularization Museum and has cooperated with its partners to complete this project. Diheng projectors have a projection ratio of 0.44, which meets the installation requirements for a short-distance space. When multiple projectors are fused, their color performances are similar, avoiding repeated adjustments, and saving a lot of time and energy for the subsequent debugging of the Science Popularization Museum. With rich and vivid color performances, the projectors can vividly present scenes such as forests, seas of flowers, and cities, and have received unanimous praise from partners and customers. According to research, human influence is the most important factor causing the non-natural death of Chinese white dolphins. All living beings in the world coexist, and we must take better care of the global village. We don't want future generations to only recognize dolphins from pictures. The protection of Chinese white dolphins is not the responsibility of just one department. It requires creating a good social atmosphere where the whole nation participates.  

To this end, Diheng China appeals that everyone should participate in the action of protecting Chinese white dolphins and together contribute our strength for ourselves, for our next generation, and for every living being in our global village.
