In this film, "Soldiers' Oxygen Bottles" unveiled an ancient high-risk industry "Pearl Picking". As we all know, pearls grow in mussels, but mussels grow in deep water. Ancient people liked money very much, because the more dangerous the industry, the more money people earned, so the industry of "pearl picking" was derived.

In ancient times, unlike modern times, there were not so many metal jewelry and carved diamonds, but those pure natural jewelry can show their identity better! After eating and drinking enough, they slowly began to pursue gorgeous costumes and liked to cherish those wonderful pearls and treasures. As a result, many people joined this "pearl picking" industry and earned a bucket of gold for themselves. The wisdom of the ancients is unimaginable. They not only made a lot of money, but also invented many treasures to help dive.

Let's get to the point and introduce the nature of this "pearl picking" industry. First of all, you have to be able to swim, otherwise you are not qualified for this job; Secondly, you need to have good water quality, otherwise, accidents are easy to happen. There is also a more subtle requirement that the pearl picker's body should not be obese, otherwise the buoyancy is too great to swim to the bottom to pick mussels; Finally, you didn't have a cramp. If you get cramped in the water, it is easy to have a safety accident. After meeting the above requirements, you can become a qualified pearl picker.

The work looks simple, but it is actually dangerous. Because the real danger does not come from those visible waters, but from those invisible and unknown dangerous situations. After diving into the water, pearl divers not only bear the pressure of water, but also feel unknown dangers from all directions, such as piranhas, reefs and undercurrents.
