Sanjiu Building Materials continues to participate in Zhengsheng Broadcasting's "Sounds and Movements Spread Love - Qin Players Hold Up" charity tour, bringing warmth and companionship to the campus. 
This event in Changhua, in addition to the moving harp performance, was also full of children's laughter and interaction. Musician Li Zheyin not only used music to bring people closer, but also used lively sharing and performance to make the atmosphere lively, bringing a small concert full of surprises and joy to the children.
In addition to donating support, Sanjiu Building Materials’ colleagues also personally served as volunteers to assist with venue support and equipment arrangement. On the morning of March 24, Wang Haoquan from the Business Department went to Fenglun Elementary School in Pitou Township; in the afternoon, General Manager Chen Xinlong of the Three Digital Integration Co., Ltd. went to Xinshui Elementary School in Puyan Township to assist. 
For Sanjiu Building Materials, charity is not just about investing resources, but also hopes to accompany more children to different learning experiences through actual participation time and time again.
I am very happy to work with the organizer and partners to bring music to the campus and keep the laughter and warmth in the children's memories.

Use it and give back to the society｜PART 2 (3/24-Changhua venue) A small concert full of laughter!

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.

We won the recognition as an excellent civil engineering supplier from Mainland China. With just over 50 of the more than 3,000 qualified suppliers receiving recognition, it means a lot to us to receive this recognition. This is not just an award, but also represents the trust of the cooperative units in our professional capabilities, quality requirements and on-site cooperation. Thank you to every partner for your input, and also to our cooperating units for their support and affirmation. We will continue to make every cooperation better and let trust accumulate into more long-term value.
