On the outside of the city wall, in the direction of meeting the enemy, there is a two-meter-high toothed crib, which is used by combatants to observe the enemy and cover themselves when shooting at the enemy.

The concrete structure is as follows: when the floor on the wall is built to the height of human chest and abdomen, the crib mouth is built again. The crib mouth is generally rectangular. There is a small square hole in the upper part of the crib, which is the observation hole. The bricks on the left and right sides of the observation hole are splayed inside and outside, which is convenient for observing the enemy and is not easy to be shot by the enemy's arrows. There is a small square hole below, which is the perforation of the bow and arrow. The bottom of the perforation is inclined downward, which is convenient for shooting the enemy at the gate.

Question 5: What is a "battlement"? Pingyao Ancient City is located 90 kilometers south of Taiyuan City, Shanxi Province. It is an obscure town, but it is the best preserved ancient city in China and one of the world historical and cultural heritages approved by the United Nations. Pingyao ancient city was built in the Western Zhou Dynasty, with a history of more than 2,000 years. At present, there are the best preserved ancient wooden structures in China, such as the main hall built in the Five Dynasties and the Jin Dynasty. In addition to these cultural relics, Pingyao City has another feature: quadrangles. There are 3797 traditional quadrangles in the city, most of which are still in use. From these houses in Gaomen Courtyard, we can see the prosperity of Pingyao in history. In the Qing Dynasty, Pingyao was called "Little Beijing" because there were powerful businessmen in the town. Among them, eight major banks headed by them operated foreign exchange business in 45 cities across the country, and even Rishengchang's name could be seen in San Francisco and new york in the United States, showing its wealth. Antique, the city wall is intact; Streets with flags flying; Ming and Qing style gatehouse; Magnificent, tall and gloomy deep house compound ... as soon as you walk into Pingyao, you will see what you see, without looking for it or exploring it. The meaning of Pingyao seems to be in an ancient word, so every household knows how to write ancient Chinese. Their pride is everything their ancestors created a century or two ago, wealth, market, facade, and a mythical history of getting rich. It was evening when I arrived. I have booked an inn in the ancient city by telephone. It says you should not be slaughtered. When you arrive, no matter where you call, a car will pick you up. So I called as soon as I got to the train station. I didn't expect the "car" to pick me up was human tricycles. Only then did I realize that I was measuring an ancient city with a sense of modernity? This is just the beginning of an interesting experience. I like to learn about a city from the night. After entering the ancient city, most shops were closed, street lamps were dim, and only a few red lanterns were flashing in the street. The tricycle driver pedaled hard and turned left and right in the ancient city. Although the ancient city under the shadow of night still has traces of noisy and lively during the day, everything has become careless. What are the dreams of this famous commercial city tonight? Went to the jstars yard. The taxi pulled me to Qiaojiabao Village in Qixian County, and I went in, almost going in the wrong lane. Many new buildings are under construction. I don't know whether the residents are building their own houses or what centers are planned in a unified way. This is a very ordinary village. Qiao Guifa and his descendants who went out from here were extremely rich through their own hands' labor, but they did not settle in big cities. They returned to their hometown and built big houses and mansions. Look at the most gorgeous mansion in this village, and you can imagine how beautiful and brilliant the jstars are in the eyes of the villagers. Shanxi's architectural style, with blue bricks and gray tiles and high walls and courtyards, is not graceful, subtle or feminine, as simple as the land itself. In fact, everything about them, including their thinking, is closely related to the land. In Pingyao after dark, except for the brightly lit restaurants and shops in the east, west and south streets, the residential alleys were dark and silent, except for a pair of red lanterns hanging in front of one or two doors occasionally, indicating that this was a family door. During the Spring Festival, there are still some places where the lights are dim. Go north along the North Street and walk to the entrance of the archway of the ancient city. You can already see the light and shadow of the ancient city wall dressed up in excitement. It seems that a play is about to be staged. Buy a ticket and go upstairs. There is a Lantern Festival here to welcome the Spring Festival. From Gongjimen to the west gate, there are themed and themed lanterns all the way. Take a closer look, everything is rough, only the paper-cut posted on the light box looks good. I think it should be beautiful to overlook the ancient city from the crib of the city wall. Unfortunately, I can't see the inside of the city clearly when I go upstairs at night. I stood in the northwest corner and looked out. It was dark and there was no light. All the lights come to decorate the city wall. The scenery of a hundred years ago can be seen everywhere here, but time has not turned back in my feeling. I know that I am standing in an ancient city that has been restored through hard work. And such efforts continue. More and more folk museums are being renovated, and the folk hotels with splendid reception history are getting older. In the street, the rickshaw owner wore a jacket and black sunglasses, gloating, and there was a piece of cardboard next to it, which was covered with photos of people sitting in his car with him. He showed me his glorious history and motioned me to seize this rare opportunity. I wonder, if I sit on it, can I feel the feeling of a hundred years ago, the feeling of a lady or wife of that era?
