Liskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types. In other words, in the process of software development, after the subclass replaces the parent class, the behavior of the program is the same. Only when the subclass replaces the parent class and the function of the software is not affected can the parent class be truly reused, and the subclass can also add new behaviors to the parent class. In order to look at an example of violation of LSP principles, the specific code is as follows:

II. Operation:
Looking back on this social practice, I have learned a lot, learned a lot of social experience from everyone I contact, and improved my potential, which I cannot learn in school. It takes long-term practice to be good at communicating with others in society. In the past, I did not have the opportunity to work, which made me unable to adapt to changes when talking with others and made the conversation silent. This was very embarrassing. People will integrate into the social group in the society, and people will work together to make the process of doing things more harmonious and get twice the result with half the effort. You should listen to the opinions given to you by others and understand them patiently and modestly. Be confident in your work. Confidence is not a numb boast, but an affirmation of one's potential. Lack of social experience, lack of academic qualifications and other reasons will make self-confidence lack. In fact, anyone who is born with confidence can overcome psychological barriers and everything will become easy to solve. The accumulation of knowledge is also very important. Knowledge is like human blood. Without blood, one's body will weaken, and without knowledge, one's mind will dry up. The brewing industry contacted this time is very strange to me. If I want to do a good job, I must understand this knowledge and have in-depth understanding of all aspects so as to better apply it to my work.
