In the above code, we use three functions, order500, order200, orderNormal to handle its own business logic, If the current own function cannot handle things, We pass it to the following function to handle it. By analogy, Until there is a function that can handle him, Otherwise, the responsibility chain mode will leave the chain directly, telling that it cannot be processed and throwing an error prompt. Although the above code can be used as the responsibility chain mode, we can see from the above code that the Order500 function depends on functions such as Order200, so there must be this function, which also violates the open-closed principle in object-oriented. Let's continue to understand writing flexible and detachable responsibility chain nodes.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.长衫、旗袍、凤眼、纤腰一搦、仿佛从浮沉往事中走出来的古典美人，这是女主。眼里盈盈的都是透亮的水，水里面养着情根，美的惊心动魄、有才的惊心动魄，被欺凌过被嘲笑过但依然长成了枝繁叶茂笑傲所有人的模样，这是男主。I also understand why the mage team is so strong now.
