Great Wall of China

Wall underpinning is a construction technique used to strengthen and stabilize existing walls or foundations that may be experiencing settlement or structural issues. This process involves excavating beneath the foundation to add support, often through the use of concrete or other materials to create a more solid base. It helps to prevent further movement and ensures the integrity of the structure, especially in cases of soil erosion or changes in load-bearing conditions. Wall underpinning is commonly employed in both residential and commercial buildings.

The pharyngeal wall is the muscular structure that forms the sides and back of the pharynx, a part of the throat located behind the nasal cavity and mouth. It consists of several layers, including mucosa, muscle, and connective tissue, and plays a crucial role in swallowing and respiratory functions. The wall is composed mainly of three muscle groups: the constrictor muscles, which help in pushing food down the esophagus, and the longitudinal muscles, which assist in elevating the pharynx during swallowing. Proper function of the pharyngeal wall is essential for effective communication and safe passage of food and air.

The Great Leap Forward, initiated in 1958, aimed to rapidly transform China from an agrarian society into an industrialized socialist state.
