What does the lighthouse symbolize?

The lighthouse symbolizes hope because it is lit by fire.

Lighthouse is a tower-shaped luminous beacon built near the key part of the waterway, and it is a fixed beacon. Its basic function is to guide ships to sail or indicate dangerous areas (often used to mark dangerous coasts, dangerous sandbanks or reefs and navigation channels leading to harbors).

With the rapid development of science and technology, and the establishment of integrated navigation systems such as radar transponder, DGPS system and AIS automatic ship identification system, the navigation function of lighthouse is weakening and its navigation value is decreasing. However, it has potential historical and cultural value and has become a human geographical coordinate sought after by all countries.
