As a functional component of architecture, windows can provide ventilation and lighting, as well as shelter from wind and rain. In Chinese culture, windows are still a beautiful scenery. I.M. Pei, an architect, said: "In the West, a window is a window, which puts light and fresh air into it. But for the Chinese, it is a picture frame, and the garden is always outside." This remark reveals the aesthetic significance of windows in Chinese architectural culture. Without going to the garden, how could one expect the spring scenery to be like this Leaking windows are undoubtedly an architectural form that adds color to gardens. As the name suggests, a leaky window is a type of window that leaks without a closing function, commonly known as a flower wall head or flower wall hole. In the Ming Dynasty's "Yuanye", it is referred to as a "leaky brick wall" or "leaky wall", usually built on top of garden walls and corridor walls, to increase the depth of the viewing angle and extend the landscape. Mencius said, "Those who exist in people are not good in their eyes." The best way to observe a person is to look into their eyes. Leaking windows are known as the eyes of classical gardens. If classical gardens are a beauty, leaking windows are her shining eyes. Generally, windows have both open and closed functions. The shape of the leaky window is unconventional, with a transparent whole and various hollow patterns in the interior of the window openings. This construction obviously has some clever ideas. The original "Construction Law" records: "Garden walls are often open and uneven, with various patterns and loopholes made of bricks, tiles, and wooden strips for easy viewing, seemingly with the intention of avoiding the outside and hiding the inside." It can be seen that viewing the scenery, distinguishing between the inside and outside, and creating an artistic conception are the essence of window aesthetics. The development of leaky windows went through the early stages of the Song Dynasty, with exquisite decoration in the Yuan Dynasty, exquisite craftsmanship and elegance in the Ming Dynasty, and complex patterns in the Qing Dynasty. There are two types of leaky windows: empty windows and stained windows. An empty window is a window opening left on the wall without a window core, often used to frame or borrow scenery. Flower window is a window core decorated with various hollow patterns inside the window frame. In addition to borrowing scenery, flower windows can also reflect the owner's interest and character. Structurally, a leaky window is generally composed of an outer frame, an inner frame, and a window core. According to the production materials, leaky windows can be divided into wood carved leaky windows, brick carved leaky windows, tile leaky windows, glass leaky windows, stone leaky windows, iron leaky windows, etc. Wooden carved leaky windows are delicate and lightweight, but not easy to use in outdoor environments. The stone leaky window is sturdy and suitable for outdoor environments. The brick leaking window is made of irregular bricks. Tile leaky windows utilize the natural curved shape of tiles to create a graceful pattern, with a lower cost. The pattern of the leaky window frame and window core is not limited to one style. There are usually abstract, natural, and symbolic forms. Abstract patterns are often composed of straight lines, arcs, and circles. Linear patterns include square, cross shaped, loop shaped, cross shaped, ice crack, etc; The curved shapes include Ruyi, Fangsheng, Baoping, mullion and soft foot patterns, lantern brocade, and Huiyun patterns. Natural patterns are mostly concrete patterns, including plant patterns such as plum blossoms, orchids, bamboo, chrysanthemums, crabapples, pomegranates, and lotus flowers, as well as animal patterns such as birds, dragons, butterflies, carp, and cranes. Integrated form patterns, combining text with abstract patterns, such as text patterns symbolizing auspiciousness such as "fortune, fortune, longevity, and happiness". The leaking window itself has high aesthetic value. The scenery seen through the leaky window is even more varied. As stated in "Yuanye", "The pavilions are tall and refreshing, the windows are empty, they embrace a thousand hectares of vast ocean, and capture the beauty of the four seasons. The charm of the leaky window is exquisite, and its overall design combines form and quality, with rich connotations. Leaking windows not only have formal beauty, but also rich connotations. Ice patterns symbolize 'ice and snow are clever'. Cloud patterns symbolize auspiciousness, and in the "Astronomical Records" of the Book of Han, it is said that "seeing the clouds brings joy and happiness". The "Sheng" in the Fangsheng pattern was originally a hair accessory worn by the Queen Mother of China and the West in ancient mythology, symbolizing longevity and health. Folding fan was a standard accessory for literati in ancient times and a symbol of their interest; The legend of the treasure vase is a Buddhist artifact, symbolizing peace. The leaky windows come in various shapes and are designed according to the scenery, imbuing the deep and secluded atmosphere of the garden everywhere. The poem "Spring Sun" by Zheng Gan in the Song Dynasty depicts the scene of light and shadow blending inside and outside the leaky window, with the line "The blue rainbow leaks through the window and the spring sun rises high". Frame scenery is one of the landscaping techniques in gardens, which uses door openings, window openings, colonnades, and other elements to frame the scenery in the garden. The creation of the artistic conception of garden landscape through leaky windows is all within a "frame". People can appreciate the static beauty of the patterns and decorations on the leaky window itself, as well as the dynamic beauty borrowed from the "frame" of the leaky window. Moving step by step, the leaky windows on the garden walls and corridors can instantly present different beautiful scenery, making the entire garden full of vitality and charm. The leaky window frame scenery is full of changing fun. The four seasons flow, with changes in sunshine and darkness. The flowing scenery is captured by the window, forming beautiful frames. Just as Li Yu said in the Ming Dynasty, "Time changes, not a certain form." Moving one step, changing one image, turning one glance, changing one scene, the eye is dazzled. In the Qing Dynasty, Sun Wen's picture book "Dream of the Red Chamber" extended the charm of leaking windows to leaking walls and screens. Li Yu said, "Opening a window is never better than borrowing scenery. Borrowing scenery is a unique technique for creating the artistic conception of Chinese gardens. In "Yuanye", it is said: "Borrower: Although the garden is different from the inside and outside, the scenery is not limited by distance, the clear mountains are towering and beautiful, and the blue sky is towering in the sky; wherever the eye reaches, the common is screened, and the good is collected, without distinguishing between towns and villages, all are misty scenery, which is the essence of the aesthetic of borrowed scenery. The fun of borrowing scenery lies in the distance. Landscape architect Chen Congzhou said in his book "On Gardens (IV)": "The space between gardens and architecture is deep and shallow when separated, and the logic is very clear." The continuous separation through windows creates a viewing effect where the interior is transparent and the scenery is within the scenery, while the exterior is borrowed and painted. In Chapter 17 of "Dream of the Red Chamber," there is a description that goes: "Jia Zheng and others walked in, but before entering the second floor, they all got lost on the old road. To the left, there was a door to open, and to the right, there was a window temporarily separating them." The landscape created by the partition appears intricately in the slanting shadows. The essence of Jiangnan gardens is summarized in the book "Yuanye" as "skillful in borrowing from the cause, refined in the body". The essence of "borrowing from others" is to adapt to the situation and arrange according to the situation, extending the local appreciation space and introducing richer scenery. There are over 400 patterns of leaking windows in Suzhou gardens, and there are 108 types of leaking windows in the Canglang Pavilion. The composition is not limited to one style, the imagery is complex, and the carving is exquisite, each reaching its own perfection. The Humble Administrator's Garden is inlaid with 25 leaky windows of different shapes on the white wall of a corridor, just like the three-dimensional Paper Cuttings on the pink wall, which is lively, elegant and elegant. The stage design of the original dance drama "Dream of the Red Chamber" is quite ingenious, with the use of a leaky window as the background and the Moon Cave Gate as the backdrop. Dancers traverse inside and outside the gate, becoming important props to drive the plot and scene transitions. The beauty of a garden lies in its poetic and picturesque atmosphere, which nourishes the mind and soothes the spirit. According to Wen Zhenheng's "Changwu Zhi" in the Ming Dynasty, gardens "make those who live here forget their old age, those who live in them forget their return, and those who visit forget their weariness". As the eyes of gardens, leaky windows have played a significant role in pleasing the eye and bringing joy to the mind. In the construction of contemporary living aesthetics, leaky windows are also highly favored, and designers widely use them in landscape, interior, and object design. Modern cities often have numerous buildings, narrow streets, and a lack of scenery. The method of "hiding if you want to expose" and "borrowing scenery" can be applied to scenes on the streets and alleys, which can extend space, add scenery, and enrich visual experience. To enable people to have the idea of 'galloping across the river, clouds, and spring trees' while living in the bustling city. The screens, courtyard lights, and other elements of the Beijing Olympic Village have been redesigned with patterns such as the ten thousand character pattern on the leaking windows, giving the modern landscape traditional aesthetic appeal and increasing the cultural recognition of the landscape. Suzhou, the city of gardens, integrates a large number of garden architectural elements, including leaky windows, from bus and subway stations to small gardens in the neighborhood, from modern residential buildings to museums, especially in interior decoration. The interior decoration of the West Hall of Suzhou Museum uses leaky window elements, combined with new materials and techniques, to complement the simple modernity and quaint elegance. The exquisite leaky window pattern has become the source of inspiration for the design of objects. The common pattern on the leaking window is the crabapple flower, also known as the "Jieyu Flower" or "Flower Noble Consort". When paired with the magnolia flower, it symbolizes "wealth and prosperity in the Jade Hall". Designers use digital technology to creatively reshape their classic graphics and integrate them with lighting design, giving traditional patterns a modern feel with simplified graphics, creating wall decorations that integrate lighting and viewing functions. Aesthetician Zong Baihua once said, "The first step in creating a beautiful object is to create a space." As a representative of the art of space, leaky windows, a form of architecture from classical gardens, can still add a touch of liveliness and romance to our cities today. (New Society)
