On August 23rd, Changsu's Family Open Day was held as scheduled. Join your family to explore the "Membrane Magic" of materials science in a world-class materials science park.
This was more than just a family party; it was an open experience combining materials science popularization, intellectual challenges, public welfare initiatives, and emotional connections. Five themed areas were specially designed around the core theme of "Materials Science," presenting materials technology to every family in an interactive, fun, and tangible way.
First Stop: A First Experience with Materials Science - Touching the Threads of Technology
From the water-gelling "Water Mist Beads" to the color secrets of PA materials in "Iodine CP," from the wonderful tactile sensation of hydrophobic "sand that doesn't get wet," to the vibrant colors in "Membrane Magic Printing," and hands-on assembly of maglev trains, hand-cranked generators, and hydraulic robotic arms, children understood the properties of materials in real-world experimental settings. Science was no longer a distant concept, but a tangible and creative experience.

The second stop: "The Strongest Brain" - A Challenge of Wisdom and Collaboration
Six intellectual challenges, including maze solving, code decryption, one-stroke drawing, and microscopic material identification, not only test logical thinking but also foster teamwork within families. Children focus intently on solving problems, while parents offer encouragement. Each successful completion is a double victory for both intellect and emotional connection.

The third stop: Family Fun Zone - Turning Imagination into Gifts
DIY straw hats express summer fun, children unleash their energy in the ball pit, catch their first "little friend" in the fishing pond, and capture their first impressions of future technology in the AI Dream Photo Studio. This is not just a playground but also an incubator for parent-child bonding and creativity.

The fourth stop: Charity Replenishment Station - One Purchase, Two Warmths
In addition to promoting materials science and increasing public understanding of the materials industry, we have also established a special charity agricultural assistance zone. All proceeds will be used to help disadvantaged groups. A refreshing drink and a snack replenish energy and convey goodwill. We firmly believe: Technology for Good, Responsibility Together.

Fifth Stop: Materials Science Confessions - Hearing the Voices of Every "Family"
In front of the camera, children say, "I want to be a scientist," and parents say, "He was more focused than me today." These genuine voices will be recorded, becoming a warm archive of the Zhonglun family.
Harvest Moment: Knowledge and Gifts Abound
Through intelligence and collaboration, families won science toys, creative cultural gifts, home appliances, and technological gadgets, leaving each family with a wealth of knowledge and gifts.

On this day, materials were no longer cold jargon, and science was no longer a distant concept. A warm, insightful, and broad family open day made technology tangible, family bonds palpable, and philanthropy feasible. The best companies not only create products but also shape the future. The best times are not only about gathering but also about growing together.

Xiamen Changsu Industrial Co., Ltd. (hereinafter referred to as "Xiamen Changsu") was established in 2009. It is a technology-based membrane material enterprise integrating "product research and development, intelligent manufacturing and application promotion" and a globally renowned supplier of high-performance membrane materials. Among them, the production and sales volume of high-functionality BOPA membrane materials are world-leading.
