Visitor pattern decouples the data structure from the operations acting on the structure, making the operation set relatively free to evolve. Visitor pattern is suitable for systems with relatively stable data structure and easy change of algorithm. Because visitor mode makes it easy to increase algorithm operation. If system data structure objects are easy to change and new data objects are often added, visitor mode is not suitable. The advantage of visitor mode is that it is easy to add operations, because adding operations means adding new visitors. Visitor mode centralizes the relevant behaviors into one visitor object, and its changes do not affect the system data structure. Its disadvantage is that it is difficult to add new data structures. -From Encyclopedia

What is the legendary Sous Vide
Wuli Bridge, commonly known as "Anping Bridge", spans the bay between Anhai Town in Jinjiang and Shuitou Town in Nanan. It was built in Shaoxing, Song Dynasty, in the 8th year (1138 A.D., the photo year of Wuli Bridge) and was completed in 13 years. The stone pier Liang Shi Bridge built of granite is the leading long bridge in ancient China. It is known as "there is no bridge in the world and this bridge is long". It is well-known at home and abroad and has been announced by the State Council as the first batch of national key cultural relics protection units. The bridge is 2255 meters long and has 361 square, boat-shaped and semi-boat-shaped piers. The bridge deck is 3-3.8 meters wide and the bridge deck is 5-11 meters long, weighing up to 25 tons. Stone guardrails are on both sides. There are five pavilions on the bridge: the "Transcendent Pavilion" in the east of the bridge, the "Haichao Temple" in the west of the bridge, and the "Surabaya Pavilion" in the middle of the bridge. One road pavilion is set up at each end for tourists to rest. "Surabaya Pavilion", commonly known as "Zhongting", has a pair of couplets on the stone pillars in front of the pavilion: "There are Buddha Zongsi Buddha in the world, and there is no bridge in the world to grow this bridge". There are two stone carvings of generals. On the side of the pavilion, 14 inscriptions have been restored in past dynasties. At the western end of the bridge pavilion, there are inscriptions rebuilt in the Qing Dynasty, and at the eastern end there is a five-story hexagonal pavilion-style wooden-like white tower. After 800 years of vicissitudes, Anping Bridge has become a "land bridge". From 1980 to 1985, the state allocated funds for maintenance, and the original appearance of the Song Dynasty was restored.
