马上就有另外的书生上前来，也不问板栗能不能做到不纳妾不娶侧妃了，直接问：王爷如此坚持，是否跟老王妃教导有关？学生听说，张家两代王爷都不曾纳妾，小辈更是连房中人都不许收，难道老王妃如此善妒？旁边有位中年书生沉声喝道：子旋不可无礼。
However, this state can be modified.

七年前罗力亚（郑嘉颖 饰）是法律界传奇，因自他执业以来，技术上未曾输过一单官司。但利用法律为自己争名逐利而受到良心的谴责，从法律界消声匿迹。七年后，见尽人生百态的力亚，跟表弟米佐治（林子善 饰）及好友丁家富（李璨琛 饰）在深水埠成立了民间法律咨询中心。他们因经常以出位手法协助草根阶层争取合法权益，成了深水埠的人民英雄，并一改法律只属有钱人专利的想法。同样是大律师的王思苦（胡杏儿 饰）本来十分仰慕当年战无不胜的力亚，如今看见他沦落为地痞律师，做人态度吊儿郎当，每次碰面都对他嗤之以鼻，但二人经过数次在法庭上交手逐渐变得惺惺相惜，甚至萌生爱意。但思苦为爬上精英阶层，设法靠拢城中擅于玩弄法律技巧的名牌大状蒋柏奇（石修 饰），结果招致官非缠身，力亚为了护花竟以身试法......

隋朝末年，天下大乱，各路诸侯，自立为王，十三个平民百姓被乱世所害，逼入绝境。他们怀着家仇国恨，循入空门。但是黑暗势力依然不放过他们，死亡当头，他们为求自保，苦练武功为了天下太平，这十三个和尚救护明君李世民，灭掉了凶残的王世充，演出了一曲英雄壮歌。
The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.
