A scholarship represents not only encouragement, but also recognition of a child’s hard work and persistence. 
Sanjiu Building Materials has long-term support for the Hawk Inline Skateboard team and is very happy to share the glorious moment with the children in this annual scholarship award event. 
From the sweat on the training ground to the smile at the award ceremony, every step accumulates growth and allows people to see that dreams are sprouting. 
We always believe that giving back to the society is not just a slogan, but through actual participation time and time again, accompanying more children to bravely pursue their dreams and move forward steadily. 
Congratulations to all the winners, may this recognition be your strength to move forward.

Accompany your children to pursue their dreams bravely and let your efforts be seen

The world is big and deserves to be explored gently. 
Sanjiu Building Materials is honored to take practical actions to support the children in embarking on a "Sealine Aquarium × Gaomei Ecological Journey" full of learning and laughter during the winter vacation. 
In the Taichung Aquarium, children observed marine life with focused eyes and recorded every new discovery; they walked into the Gaomei Wetland and personally felt the pulse and vitality of the natural ecology. In addition to studying, we also accumulated precious time for each other's companionship and growth through group cooperation, sharing meals and communication. 
We believe that the value of a company is not only reflected in its products and technology, but also in its care and investment in society. 
Being able to accompany children into the world, understand nature, and leave them with a warm childhood memory is the original intention of Sanjiu’s continuous investment in corporate social responsibility. 
In the future, Sanjiu will continue to support more meaningful public welfare and educational activities with actions, so that goodwill can slowly accumulate and continue to spread in society.

The most innocent smile from a child is our most precious feedback

Thank you children for giving back our most precious touch with their smiles&nbsp;
It is a great honor for Sanjiu Building Materials Industry to accompany children to overcome fear step by step and gain confidence and courage&nbsp;
We believe that every well-supported learning can become a force for children to move forward in the future&nbsp;
May this companionship become the starting point for children to continue to bravely move forward&nbsp;

Accompany children's growth and witness the blooming of confidence and courage

Sanjiu Building Materials continues to support public welfare with actions. This time, we participated in Zhengsheng Broadcasting's "Sound and Love" charity trip. In addition to donating support, company colleagues also personally went to Nantou Puli Rural Primary School as volunteers to assist with venue layout, activity support and equipment arrangement. In the morning of March 12, deputy managers of the management department Lai Yijun, Cai Yiting, and Huang Jiayi went to Taoyuan Elementary School; in the afternoon, Sanjiu Building Materials partner Li Chengen went to Qilin Elementary School to assist. For Sanjiu Building Materials, charity is not just support, but also personal participation; it is not just the investment of resources, but also the real care brought to the scene. I am very happy to work with the organizer and all partners to bring music, companionship and warmth to the campus, leaving a special learning and experience for children in rural areas.

Use it for society and give back to society. Sanjiu participated in [Sound and Movement Love Charity Tour] PART 1

Today we are at the "Kaohsiung Architectural Society" membership meeting! ✨&nbsp; This is a grand event for the architectural community in southern Taiwan, gathering many professionals in architecture, urbanism, and landscape, as well as creative students from colleges and universities. We displayed our core products on the 5th floor of Hanxuan Hotel. I saw many architects and students stopping in front of our booth to learn more about the characteristics and advantages of the products. It was really a lot of benefit to have in-depth professional exchanges with you! Thank you to everyone who came to the booth to communicate today. Sanjiu Building Materials will continue to provide more complete products and services to accompany the construction space in a safer and more practical direction.
