Lighthouse and Light

An old man with white hair, a lighthouse standing on the seaside. The old man lights the lighthouse, and the lighthouse gives him spiritual comfort. But times change, new lighthouses will replace new lighthouses, and the old man's lighthouse can only be extinguished forever. Thousands of sails pass by the side of the sunken boat, and thousands of trees spring in front of the diseased tree. Everything is inseparable from change and replacement. It is not only the lighthouse in the article, but also life!
