Preface: The Wanliang Ancient Post Road, as an important land route hub connecting Wanzhou and Liangping in ancient times, is the essential passage for Jingchu, Wu, and Yue regions to enter Sichuan and reach western Sichuan. It is also a key component of the "Litchi Road", carrying the thousand-year historical memory of "a horse riding through the dust, making the concubine laugh", connecting the past prosperity of Chang'an and the Shu region, and witnessing the cultural integration between the southwest and the Central Plains.

Recently, the administrative functional departments of Chongqing Sanming Heavy Industry organized a 10-kilometer public welfare hiking team-building activity along the Wanliang Ancient Post Road, with the theme of "Traversing Ancient Paths to Recall Civilization, Practicing Public Welfare to Protect Nature". Sanming people temporarily left their desks and stepped into the green mountains and clear waters, measuring the historical depth of the thousand-year-old ancient road with their feet and conveying their responsibility and commitment to green environmental protection through their actions.
"The Sichuan Road is steep and treacherous, reaching high into the sky, and at the Qin Pass, we halt our horses to gaze upon the western plains." For administrative staff who spend years working at a desk, this hiking trip is not only a dual training of physical fitness and willpower, but also an immersive public welfare practice. On the way, the team members held tools in hand, meticulously cleaning up waste along the ancient road, strictly adhering to the environmental protection concept of "leaving no trace except footprints," integrating the original intention of public welfare into every step forward, and letting civilized actions preserve the style and features of the ancient road.

The sunset glow accompanied our return journey, leaving us physically exhausted yet spiritually enriched. This activity not only helped everyone gain a strong physique and team synergy, but also allowed us to appreciate the historical heritage by touching the ancient road relics and cultivate a deep sense of awe while being close to nature. The tenacious strength and ecological sentiment derived from the ancient road will be transformed into a driving force for progress in our work, empowering Sanming people to delve deeper into their positions and fulfill their mission with a more vigorous attitude.

In the future, Chongqing Sanming Heavy Industry will continue to deeply engage in public welfare practices, create more team-building activities that embody both cultural connotations and social responsibility, align enterprise development with nature conservation, and resonate industrial value with cultural heritage. Together with all employees, we will create value while deeply cultivating social responsibility, embarking on a new journey of harmonious coexistence with nature, history, and society.

Introduction: In December 2024, East Hope Group's Chongqing Fengdu Phase I sand making building issued a bidding announcement for technical renovation. Chongqing Sanming Heavy Industry emerged with its superior performance advantage of the VCX ultra-fine sand making machine, replacing one vertical shaft impact crusher and one roller mill with one VCX ultra-fine sand making machine. In July 2025, the company's Phase III sand making building underwent another technical renovation, and Sanming Heavy Industry's VCX ultra-fine sand making machine successfully replaced two of the six sand making machines in the building, achieving a repeat purchase of VCX ultra-fine sand making machines.

Repurchasing is the greatest trust and recognition that customers have for a product. Recently, in the technical renovation project of the sand making building in the third phase of Chongqing Fengdu, East Hope Group once again purchased two VCX ultra-fine sand making machines from Chongqing Sanming Heavy Industry to replace two of the six sand making main machines. Currently, four of the six sand making main machines in the sand making building have adopted the VCX ultra-fine sand making machines from Chongqing Sanming Heavy Industry, achieving three repurchases of products.

Three times of repurchasing VCX ultra-fine sand making machine have been installed in place

Three repurchases witness excellent quality: the performance advantage of VCX ultra-fine sand making

• High productivity and low energy consumption: Single motor operation, integrated motor design, compared to traditional sand making main machines, energy-saving motors consume 50% less energy, saving millions of electricity bills per year for a single device. Moreover, the sand making efficiency is greatly improved, and the output is increased by 20t/h on the original basis
•Efficient powder reduction: Adopting a five-stage crushing chamber design with adjustable crushing chamber gaps, it achieves a precise powder reduction of 10 percentage points compared to traditional sand making main machines, successfully reducing stone powder by 5% on the original basis.
•High finished product quality: The finished sand produced by the VCX ultra-fine sand making machine has good particle shape, with a circularity greater than 0.82, and excellent continuous grading, meeting the material standard for medium sand in Zone 2.

Customer satisfaction: the greatest compliment to a product

According to the production manager of the project, "After several technical modifications and verifications, Sanming Heavy Industry's VCX ultra-fine sand making machine has exceeded expectations in terms of stability, sand output quality, and energy consumption. This is the reason why we chose to repurchase it again."

With a long-term perspective, we strive for innovative development. Chongqing Sanming Heavy Industry has always been committed to achieving mutual value with our customers. We firmly believe that only product technologies that can withstand market scrutiny can earn long-term trust and support from users. Every repeat purchase marks the beginning of a new partnership. Sanming Heavy Industry looks forward to collaborating with more industry partners, leveraging our technical expertise and service guarantees to deliver satisfaction, and jointly creating a bright future for the sand and gravel industry!

To thoroughly study and implement the spirit of the Fourth Plenary Session of the 20th Central Committee of the Communist Party of China and gain firsthand insights into the great achievements of poverty alleviation, the Wanzhou Economic Development Zone Chamber of Commerce recently organized a themed party building activity in Zhongyi Township, Shizhu Tujia Autonomous County. Chongqing Sanming Heavy Industry, as an important member unit of the Chamber of Commerce, embarked on this meaningful red learning journey together with other participants.

Following the footsteps of General Secretary Xi Jinping's inspection, we entered the "Original Intent Courtyard" and the Historical Exhibition Hall of Poverty Alleviation in Huaxi Village, Zhongyi Township. The simple physical objects and precious pictures vividly reproduced the hardships and glory of this great campaign. Being immersed in the scene, we were deeply shocked and gained an unforgettable understanding of the spirit of poverty alleviation, which embodies "unity, determination, precision, pragmatism, innovation, and perseverance to overcome difficulties and live up to the people's expectations". This experience has further strengthened our original mission of serving the country and society through industry.

Subsequently, we listened to a special party lecture given by Secretary Wang Xiangsheng of the Zhongyi Township Party Committee, who integrated the spirit of the Fourth Plenary Session of the 20th Central Committee of the Communist Party of China with grassroots practices, providing us with a profound ideological baptism. The stories of the cadres and the masses in Zhongyi Township forging ahead with determination made us deeply realize that adhering to the comprehensive leadership of the Party is the fundamental guarantee for enterprise development. We must integrate the Party's innovative theories into the blood of the enterprise to ensure that the development direction remains undeviating and the momentum never falters.

In Qiaotou Town, Shizhu County, we visited the Taoranju Wawu Town and Art Sketching Base. These exemplary projects integrating culture and tourism allowed us to witness the vigorous vitality of rural revitalization firsthand, and also provided new ideas and perspectives for enterprises to explore industrial upgrading and cross-sector development.

This party building activity effectively deepened the consensus between the government and enterprises and fostered a joint force for development through on-site learning, theoretical study, and industrial inspection. Chongqing Sanming Heavy Industry will take this opportunity to continuously strengthen the leadership of party building, integrate the red gene into enterprise development, and demonstrate new responsibilities and achievements in the journey of the new era!
