The Bajau people get up early every morning to start a day of "sailing" and fishing, while the children dive and play in the sea around the boat.

The Bajau people are masters of free diving and can dive to depths of 30 meters or even deeper to catch deep-sea fish, pearls and sea cucumbers.

Sea cucumber is not only a delicacy of the Bajau people, but also a treasure that the Bajau people have sold to the outside world for centuries.

When diving, they all wear hand-carved wooden goggles with glass lenses and hold harpoons made from scrap materials on the ship.

In order to increase the number and success rate of catching fish and shrimps, the Bajau people who used traditional fishing gear later began to try to make homemade gunpowder and detonate it in the sea for fishing.

In addition, they also learned how to use cyanide to prolong the survival time of fish to meet the increasing demand for live fish in seafood restaurants in mainland China and Hong Kong.

According to research and analysis by the World Wildlife Fund, the industry's output value is now as high as US$800 million per year.

The Bajau tribe sings an epic song called "Iko-Iko."

If sung without interruption, this song can last for two days and two nights.

The lyrics record the history of Bayao, including where they have been, what marine life they have seen, and what messages the soul of the sea is conveying to them.

Traditional Bajau cosmology is a combination of animism and Islam, which reveals the complex relationship between humans and the ocean.

For the Bajau people, the ocean is a complex living entity, and the currents, tides, coral reefs and even mangroves all have souls.

And this knowledge and awe should be used to protect rather than destroy nature.

Long-term ocean diving operations have caused some fishermen to suffer from decompression sickness.

At the same time, because the Bajau people's activity range is located in the border areas between countries, in the past few decades, the Bajau people wandering on the sea have always had conflicts with countries with definite borders.

In order to avoid disputes and protect maritime resources, some governments of neighboring countries forced the Bajau people to settle ashore.

In the Torosiaje area, the Indonesian government continues to put pressure on the Bajau people to build stilt houses in shallow waters near the shore, and even allows them to go directly ashore and live in villages.

This has resulted in fewer and fewer Bajau people living on the traditional "lepa-lepa" boats.

This has made the lives of many Bajau people even more difficult. Although they themselves are aware of the damage caused by primitive fishing to the ecological environment, most people have not yet found an alternative way of survival.
