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

When she came to Qingdao, she had to mention Kang Yue, the pride of Qingdao women's lifting in recent years. She was not only the champion of the National Games and the national champion, but also the world champion in the World Championship. In her heyday, Kang Yue's result in the 75kg category was 30kg higher than that of the domestic runner-up, almost the king of 75kg. Speaking of the day when I first arrived at the sports school, Liu Eryong still remembers vividly, "I saw her for the first time when I was selecting materials. The little girl was dirty in this school uniform. Her family lived in a small temporary house built by the sea. Her parents made a living by fishing for sea vegetables and her family was very poor. However, she has a very good talent and worked very hard after choosing a sports school. She almost never missed classes or asked for leave. Sometimes when she was injured, she was not allowed to practice and let her rest. The child cried and begged us whether my arm was injured and I could practice my legs and waist. Don't let me rest. With talent and hard work, Kang Yue was chosen by the province after less than two years of practice in our country. In the third year, she won the championship of the City Games and began to rule the women's 69 and 75 kg categories. She ruled for 10 years. The result of Shenyang National Games was 30 kg higher than that of the second place and 50 kg higher than that of the 2012 Olympic champion. This gap is amazing! "
