2024 - LIGHT OF NOSTALGIA

Under the background of high-density cities, people’s work and life pressure increases, the living environment is bad, people’s mental health deteriorates, and people have the desire to return to the countryside.And,there are many distinctive residential villages in the Yangtze and Yellow River basins of China. They are built according to the region and climate and have distinctive courtyards and patio Spaces. With the passage of time, there is a need to improve the quality and ecology of its living environment. Firefly culture in China has a long history. In the Book of Songs of the pre-Qin period, there are poems describing fireflies like ”setting deer fields and shining brightly at night”, and Du Mu’s ancient poems also describe ”the cold picture screen of the silver candle in autumn, the light and small fan flutter firefly”. mong the large family of insects in nature, fireflies are one of the few insects that can arouse the poetry and beauty of ancient people. In addition, it is also the carrier of our memories of home. Fireflies are insects with specialized luminaires in their abdomen. Adult individuals are generally small, most of them 1 cm long. Eggs, larvae, pupae and adults glow in all four stages, preferring to roost in wet grass, hide under rocks or sand in water during the day, and come out at night to feed. The glow time is from 6:00 p.m. to 4:00 a.m.About the mechanism, the luminous efficiency of fireflies is very high, and almost all chemical energy can be converted into visible light, which is several times to dozens of times the efficiency of modern electric light sources. The light emitted by fireflies radiates little heat and produces no magnetic field, making it an ideal light. The study on the luminescence mechanism and function of firefly and its bionics, as well as the ecology and ecological environment protection of firefly will have extensive significance.The courtyard and patio space are the spatial core of residential buildings, where people cultivate flowers, trees, grass, fish, etc., with good humidity and shelter, it is a good place for fireflies to inhabit.To create a ecosystem, fireflies feed on snails that harm crops. Some species prey on small animals such as earthworms and insects. Last,The courtyard in the residential buildings falls into darkness after the evening, which loses the lighting and interest as the core of the whole building. Especially during the summer blackout, affecting people’s lives. In addition, the buildings in the village have lost their light. The introduction of firefly nurturing ecosystems allows courtyard patio spaces to gain light and vitality at night. In addition to giving people space to live poetic, avoid depression mood.Based the analysis and creation above, under the establishment of the patio firefly ecosystem, villages and courtyards come tvo life, people live poetic lives, people return to their original villages will arouse their nostalgia and memories, people’s physical and mental health will be healed.The nostalgia is echoed.
