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《礼记?曲礼上》曰：‘行。Cyber warfare is different from nuclear weapons. Countries secretly develop nuclear weapons. If nuclear weapons are deployed, citizens will suffer more than leaders. It is very likely to ensure "mutual assurance of destruction". The transparency treaty has been committed to the stockpiling of nuclear weapons by all countries and prohibiting the deployment of nuclear weapons. Perhaps the same applies to digital warfare?可是，难道今晚就白来了？难道他就要这样放弃了？带着满心的不舍，他看向紫茄，却发现小姑娘正对着他微笑。每一个字就像大锤一样击在他心头，让付宇锋有一种缓不过气来的感觉。任清泉是香港知名的书画家，在上环开设了一家卖文房四宝兼卖名家书画的店铺“多宝轩”。为了推广中华文化，还开班教授书法和国画。清泉妻子早丧，多年来与妻舅高大威和女儿芝华一同生活。芝华在北京完成了美术课程返回香港，这个慈父显得特别着紧，花尽心神为女儿打点一切。为了女儿回家，清泉快活了大半天。他说：“我一定要为女儿做一点事，否则我的心总是耿耿于怀。”这段父女关系，似乎有不为人知的内情……方子聪是IT界的青年才俊，终日和时间竞赛，令他的脾性也有点急躁。唯独他对母亲慧玲感情特别深厚，事母至孝，是母亲眼中的宝贝乖仔。子聪偶然机会下认识芝华，却误会芝华是个见死不救的人，从此对芝华毫无好感，芝华却似有难言之隐，有苦自己知……谨记舅舅教诲。
