Walking around Gulangyu Island, found "Gulang Stone"! It is a reef off the coast of Gulangyu Island, and the name of the island is said to have come from here. It is said that Gulangyu was called "Yuanshazhou" and "Yuanzhouzai" during the Tang and Song Dynasty, because the island is oval, surrounded by sandy beaches, and is known as the image. At that time, the island was full of boulders, green grass, but small and deserted. Today's Gulangyu Island is very lively. If it is not for the current management, there is really a risk of being trampled by tourists in the "Golden Week"...
