In fact, each design pattern is a very important idea, which looks very familiar. In fact, it is because what we have learned is involved. Although sometimes we don't know it, it is actually reflected everywhere in Java's own design, such as AWT, JDBC, collection class, IO pipeline or Web framework, in which design patterns are everywhere. Because of our limited space, it is difficult to talk about every design pattern in great detail, but I will try my best to write down the meaning clearly in the limited space and space so as to make everyone understand better. If there is no accident in this chapter, it should be the last talk of the design pattern. First of all, it should be the figure at the beginning of the previous article:1600多年以前的东晋末年。是一个士族与平民对立，爱情自由与传统束缚不能并存的时代。绫濑遥、高桥一生、柄本佑和北村一辉将合作TBS新剧《天国与地狱》(天国と地獄，暂译)，本剧将于2021年1月开播。绫濑遥将饰演本剧女主角、东京警视厅搜查一课的正义女警望月彩子，不幸与高桥一生饰演的高智商杀人犯日高互换灵魂，两个人从说话、生活到思维方式都发了逆转，日子变得一团糟，而柄本佑饰演的邻家自由业者渡边，和北村一辉饰演的彩子上司河原，也参与其中。本剧编剧为森下佳子(《乱世花道》《天皇的御厨》)，导演为平川雄一朗(《天皇的御厨》)、松木彩(《半泽直树2》)和青山贵洋，每周日晚9点播出。It is convenient for fighting and evacuation, and a circular fire lane should be set up. With the accelerating pace of urbanization, urban land is increasingly tight, which promotes the construction of high-rise buildings. Many high-rise buildings, due to poor consideration of fire prevention design and other reasons, have many congenital hidden dangers, and fires occur from time to time, causing heavy losses. In order to create convenient conditions for fire fighting and rescue work and ensure the safety of buildings, circular fire lanes should be set up around high-rise buildings. However, regardless of the size of the building, it is indeed difficult to require the circular fire lanes. Lanes can be set up along the two long sides of the building. In order to prevent the collapse of building components in case of fire from affecting the normal operation of the fire lane, the distance between the fire lane and the outer wall should be 5m. There should be no trees, overhead pipelines, etc. that hinder the operation of climbing fire engines between fire lanes and high-rise buildings. If the total length of the building exceeds 220m, a fire lane shall be set up to pass through the building. There is no inner courtyard in the building, there are ring fire lanes around it, and fire engines crossing the building need to be set up. Q: An L-shaped high-rise building has a total length of about 170m, a length of 120m along the street, and a length of 50m along the inner street (residential road). Do you want to set up fire lanes crossing the building? A: The relevant provisions of the "Construction Regulations" and "High Regulations" consider that there is no restriction on the length of the two wings on the premise of meeting the requirements of fire fighting and evacuation. The building only needs to set up a pedestrian passageway connecting the street and the inner courtyard at the part over 80m along the street, and there is no need to set up a fire lane. In the planning of fire lanes, in addition to the relevant provisions of the "Construction Regulations" and "High Regulations", attention should also be paid to随着客人增多，远处的也都渐渐到了。他每次出击，都简单直接，却能令人致命。乘坐快车前往Honore，一名乘客被刺死。 尽管没有人离开公共汽车，杰克和他的团队对此案感到困惑-那么他们到底是如何谋杀的呢？
