**Maritime Affairs and Maritime Safety Hall**
After visiting the exhibition hall on the first floor, we come to the second floor. Compared with a year ago, the Maritime Safety Hall is reopened. The content is very rich, telling about maritime safety issues closely related to navigation from various aspects and angles.
In fact, China’s water safety cause can be traced back to a long time ago. According to written records, officials in charge of ships were set up in the Zhou Dynasty. Calculated, it has a history of 3,000 years. With continuous development and innovation, there are more and more positions, regulations, and certificates related to maritime affairs and water. They are becoming more and more comprehensive.
Nowadays, many departments and companies maintain maritime navigation and realize global integration, which is still very powerful. Maritime safety also includes lighthouses and navigation lights on islands and reefs. These are all necessities for guiding the correct route.
At first, I didn’t understand. It turns out that a seemingly prism-like thing is actually a component inside the lighthouse lamp. It is such a complex design that there are various rays.
**Maritime Navigation and Charting**
When it comes to maritime navigation, we must mention maritime surveying and mapping. Even in ancient times when there were no professional instruments, intelligent working people used their methods to map out primitive nautical charts. Zheng He, the navigator, made seven voyages to the Western Seas and mapped as far as the Cape of Good Hope, providing important data for future generations.
**Special Commemorations and Search and Rescue**
The exhibition also has some special commemorations in special regions, such as the reefs in the South China Sea Islands, which all have commemorative significance after people arrive. Maritime search and rescue is also a very important part of maritime safety. Nowadays, the maritime rescue system is very perfect and also provides important support for everyone engaged in work at sea. In fact, rescue is not only within the scope of work but also includes ordinary people’s tourism and so on.
