Military Status of Zhonghua City Wall
The renowned defensive function of Zhonghua City Wall is the practical design of the Wengcheng (Chinese: 瓮城) which is a special castle designed with great strategic advantages in battles. There are four walls in Zhonghua City Wall in proper order, and the spaces between every two walls are called a Wengcheng; and three Wengcheng are connected by four arch doors. 27 tunnels in total were built on both sides of the three Wengcheng to storage food and weapons and can also hold about 3000 soldiers. It is a peculiar structure seldom seen in ancient China which plays a vital role in ancient wars. If the enemies entered, all the gates were closed, and the four walls can divided them into three parts, which make it easily to defeat enemy one by one.
