Therefore, the network card will do some processing when sending, filling 6 zeros at the end of the TCP header to meet the minimum packet length requirement. At this time, the length of the entire packet is 14 bytes of Ethernet header, 20 bytes of IP header, 20 bytes of TCP header, plus 6 bytes of 0 filled due to the minimum packet length requirement, totaling 60 bytes.在一场万人瞩目的比赛中，俄罗斯国家队队长尤里因射失点球导致球队惨败，而后他声名狼藉告别了绿茵场。就在尤里跌入谷底被所有人遗忘的时候，一支地方球队却意外邀请他担任主教练。面对球队的内忧外患，政府的质疑与无视，球场上各种黑幕与潜规则，尤里毅然决然地带领这支球队开启了一场为己正名的战斗。终于在他的带领下球队逆袭闯进了全国决赛，而这最后一球将决定尤里能否带领这支籍籍无名的队伍取得胜利，代表俄罗斯参加欧联 ……两人正说话，葡萄姑姑就走进来。For example, in the above column, Xiao Hong suddenly didn't want to buy shoes, so he didn't want to accept the news of the seller's store, so Xiao Hong could cancel the subscription of the store.-Guo Cheng (Sponsor of the Public Reading Association)《恋爱SOS 第二季》讲述了一个颇具戏剧性的故事，四个要债人因为同时追缴欠款凑到一起，他们想尽办法终于成功地将逃债的损友堵在十字路口，却只拿到一个行将倒闭的网站，于是合伙干起爱情委托网站。
