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:

毛骗，意思是指街头的小毛骗子，他们有组织有纪律，混迹在城市的边缘。他们是骗子，是侠盗，是不法份子，或者他们没有高尚品德，但是有职业操守，他们的目的不仅仅是为了钱。他们是高智商的艺术家，精密算计着每一步的计划，锁定目标，制定计划，精心布局，诱敌深入，最后把贪婪好色和为富不仁者收入网中。小偷看不起强盗，因为强盗没有技术含量；骗子看不起小偷，因为小偷没有艺术含量。每一件事，只要到了极致，就是一种艺术。这是一面镜子，反映社会的另一个层面。有些东西也许我们都看不到，但是我们都听说过，这是当下的故事，未来的传说。此为毛骗第二季。

We are the builders of the future of the society, so we should use our hearts to walk out of the ivory tower and go into the society to understand the national conditions and serve the society. The social practice of "three rural areas" in summer is an effective way to let us know the society, serve the society and exercise ourselves. This social practice of "three rural areas" has enabled me to understand my social position, define my mission on my shoulders, and further stimulate my enthusiasm for learning. I deeply realize that teachers are role models for students, and our words and deeds are seen by students. Therefore, while teaching students, we should also strive to improve our comprehensive quality. At the same time, I also deeply realize that teachers should not only preach, teach and dispel doubts, but also guide students to establish correct learning attitude and correct outlook on life, world outlook and values. This summer's social practice has not only cultivated our potential to apply theory to practice and the spirit of teamwork, honed our strong will, but also realized the goal of "serving the society and exercising to become a useful person" in the process of social practice. I remember someone once said: whether a graduate is a talented person or not depends on his academic qualifications and social practical experience. Because theoretical knowledge alone is far from enough, without any potential for social practice, one cannot connect with the rapidly developing society. So there was this dragon neck trip.
