The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu

Comparing the similarities and differences between the garrison forces of our army at position 169 and position 142, It will be found that there are a large number of people in position 169 (a reinforced platoon with a total of 45 people and equipped with recoilless rifles and other infantry powerful assault weapons, after being reinforced by the chemical defense squad, although the total number of combat personnel was reduced by 2 people, two 74-type flamethrowers were added, and the melee and assault capabilities were actually strengthened), The firepower is relatively strong, When the Vietnamese troops attacked here, they sent out strong defensive humanoid monsters. However, the number of people in position 142 is relatively small (only the "15 warriors" led by Li Haixin, And only equipped with rocket launchers, Without recoilless guns and flamethrowers, However, there are simple minefields with anti-infantry mines. This is better than at position 169, If a minefield is also deployed at position 169, Although it is not possible to completely kill the humanoid monster at one time, But it can certainly play a significant blocking role, To provide favorable conditions for the main position to carry forward its firepower and carry out annihilating shooting), The firepower is relatively weak, When the Vietnamese army attacked here, it sent out such small targets. Fast, unidentified creatures like "dogs", To sum up, the defense-strong humanoid monster stormed the powerful position 169, It should not be a coincidence that the Vietnamese army has certain tactical considerations when using "living biological weapons" to attack positions more suitable for its own characteristics with different "living biological weapons" instead of simply throwing themselves into the battlefield at will.
