1931年，日军入侵山海关，华北形势告急，故宫博物院决定将馆藏精品转移，以避战火浩劫。文物由北京经上海、南京辗转运抵位于大后方的四川和贵州，最后保存在乐山、峨嵋、安顺等偏远地区。至抗战结束后，陆续运回南京，之后部分被运送到台湾，部分回归北平本院，部分留在南京。 文物南迁工作历时十五年，近二万箱、近百万件文物，行程数万公里，曾经在徐州、郑州遭到日军飞机的轰炸、在峨嵋经受了大火的考验，但都能化险为夷，文物没有丢失损毁，这是中国文物保护史乃至文化史上的奇迹，也是中华文明史上的奇迹。南迁之路是一条充满艰险的道路，无数的人力物力，无比崇高的责任心，无与伦比的勇气，铺平了这条道路，其中的艰辛困苦和危急是难以想象的……

At present, what methods do we take to solve the attack? The first method shortens the waiting time and deletes the illegal request data packets waiting in the waiting queue as soon as possible. The second method is that the first handshake message is not put into the waiting queue. We return a 32-bit unsigned integer to the client as the Seq of the second handshake. The integer is obtained by adding a serial number of the server to the parameters requested by the user (including the requested address, port, etc.). If it is a normal user, it adds 1 as ACK after receiving this integer and returns it to the server. After receiving the data, the server subtracts 1 from this ACK and then performs inverse operation to obtain various parameters. Finally, the data sent out are compared. If they are completely consistent, it means that it is an effective response and stored in the corresponding data structure, otherwise it is not. Through this method, illegal requests cannot occupy system resources.
