The Chinese white dolphin, a mammal at the top of the marine food chain, lives in shallow waters about 10 meters deep off the coast of China. It is one of the few cetaceans in the world that only lives in shallow waters.Every year in the third month of the lunar calendar, fishermen begin to worship Mazu, and it is also when white dolphins become active.It is said that white dolphins can deal with sharks, and a bay guarded by white dolphins will be very safe.

Therefore, they are also considered to be the incarnation of Mazu and are called “Mazu fish”.Many people marvel at the spectacular scene of a group of white dolphins forming a circle and chasing human fishing boats, but they do not know that this is actually because the food that offshore white dolphins can hunt is getting less and less, so they have to take the risk of approaching fishing boats.However, getting close to fishing boats means countless fatal dangers such as tangled fishing nets and sharp propellers.At the same time, various human production activities such as offshore bridge construction, sand dredging, and reclamation, as well as the sound of ship engines, also seriously interfere with the sonar detection system of white dolphins, causing them to stray into the inland.
