The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.

南宋年间，武林上互相仇杀。青城派李诚为找寻传说中的剑魔神宫，率弟子闯入雪魔派所在地——圣幽谷。虽被雪魔派公主——萧玉雪(雪儿)打伤，却也进入了剑魔神宫，并误开机关，封闭了神宫。李诚最后负伤逃走。雪儿向其母——红花鬼母(已是雪魔派教主)禀告，红花鬼母得知神宫封闭，大喜。原来二十年前，因雪儿父母练红花抓骨功而被正派追杀，其父被杀，雪儿与其母被雪魔教主所救，雪魔教主见她满腔怨毒，于是说除非神宫封闭，不准出谷。现在时机已到，于是派雪儿先去。白云飞与方小虎都是孤儿，但酷爱习武，于是经常到青城派偷看众弟子练武并学习。这天他们却被发现，白云飞恳求掌门丘冯春收他们为徒，丘未应允。白云飞在青城门外跪了一天一夜，终于感动了丘冯春，遂答应收留。

由这次公布的海报可以看出《大侠黄飞鸿》或许将与万合天宜以往作品的风格都有所区别，少了许多低成本搞笑，多了几分大片的即视美感。概念海报与内容海报不同，它是将影片的元素进行碎片化和符号化的处理，是更具艺术性的创作，它传递的主要是影片的核心概念，并让影片变得神秘而有趣。《大侠黄飞鸿》的这张概念海报以人物为主体，显然是以黄飞鸿为核心内容，神秘的色彩与造型似乎在向观众宣传一个理念：这将是一个不一样的大侠。

The template method pattern defines the algorithm skeleton in an operation in an abstract class and delays the implementation of some specific steps to subclasses. The template method enables subclasses to redefine specific steps of the algorithm without changing the structure of the algorithm, thus achieving the effect of reusing codes. The specific structure diagram is shown below.
