A lighthouse is a tower-shaped luminous beacon fixed facility located on the coast, port, or river, used to guide ship navigation and ensure navigation safety.

It is often used to mark dangerous coasts, dangerous sandbars or reefs, and channels leading to port mouths.

For a long period in the history of human civilization, the role of lighthouses in maritime navigation cannot be underestimated. Due to the lack of marine navigation positioning technology in ancient and modern times, to ensure that the fleet does not lose its way at night, lighthouses built along the coast constitute the "lifeline" of ships sailing at night.

With the rapid development of science and technology and the establishment of a comprehensive navigation system including navigation and positioning system, radar transponder, DGPS system, and AIS automatic ship identification system, the navigation role of lighthouses is increasingly weakened, and the navigation value is increasingly reduced.

According to statistics, there are only about 1,400 lighthouses still in use around the world. Despite this, the potential historical and cultural value of the lighthouse has made it a sought-after human geographical coordinate and a popular outdoor tourist attraction in various countries.

The most famous lighthouse in the world is the Lighthouse of Alexandria, which stood in Alexandria, ancient Egypt, and is known as one of the "Seven Wonders of the World". It is said that this 400-foot-tall lighthouse was built in 278 BC and was destroyed by two earthquakes in the 14th century. During the 1,500 years it went through, it has been guiding sailors returning from voyages to the port in the night, becoming an immortal legend in the history of human navigation.

Lighthouses can not only become the spokesperson of the ancient navigation industry but also occupy an indispensable position in modern navigation and transportation.

The establishment of these lighthouses is like embellishing the vast ocean with dazzling gems, and more like talismans for this peaceful and fertile sea, ensuring the safety and smoothness of free navigation on the sea and always guarding this peaceful sea.

Rabindranath Tagore said: "Love is an eternal beacon. It looks at the storm but remains unmoved."

In life's journey, the warmth emanating from others, like the light of stars and fireflies, envelops us in a beautiful glow. What is more important and easy to ignore and forget is that the torch and guiding lighthouse in our hearts cannot be extinguished.

When your hopes fail one after another, you must be firm and don't give up. You have to believe that the storm is only temporary and just blocks the lighthouse's light. As long as you persist, the lighthouse will be waiting for you not far away.
