The company's name originates from the seventh-generation monarch of the Xia Dynasty: Da Zhu. Zhu reigned for 17 years, participated in the Xia Dynasty's restoration war led by his father, Shaokang, and achieved great military merits. During the war, he invented armor and spears, significantly enhancing the combat effectiveness of the Xia army. After ascending to the throne, Zhu was dedicated to governance, expanded the territory, and led the nation into a golden age, making the Xia Dynasty a truly unified empire. Zhu established great achievements in restoring the nation, stabilizing the state, and expanding the territory, enjoying a high reputation and status in the Xia Dynasty, and was a monarch who fully inherited and promoted the cause of Yu (Spring and Autumn period literature "Discourses of the States · Lu Yu": Zhu, who could lead like Yu, is thus reported by the Xia Hou clan). During the period of the Three Sovereigns and Five Emperors, when the Yellow River flooded, Yu mobilized various tribes to carry out a 20-year water control project. This not only unprecedentedly united the ancestors of the Huaxia but also established a unified management system during the process, greatly enhancing his reputation and laying the foundation for the first unified monarchy in Chinese history—the Xia Dynasty. Although the Xia Dynasty formed a unified monarchy, its rule over various feudal states and tribes was only of an alliance nature. When it came to Taikang, due to poor governance and the strength of the feudal states and tribes, the regime fell into the hands of Houyi. After Houyi's death, Shaokang and Zhu, father and son, organized the Xia people to restore the Xia royal house, achieving the Zhongxing of Shaokang, and the territory of the Xia Dynasty expanded to the east coast during Zhu's rule. Since then, Huaxia has also become a synonym for China. The process of Yu founding the nation—Taikang losing the nation—Shaokang's restoration—Zhu's golden age is also the process of establishing a unified monarchy, resolving internal troubles, and entering a golden age. Yu's water control and Zhu's armor undoubtedly played a very key role in this process. Additionally, the meaning of "zhu" includes conception (ingenious design), planning (Preface to the Collection of Wang Bo: You also silently praise the divine, not on the axis of human affairs), and pivotal (Fei Geng Collection · Cheers for the Revolutionary Civil Rights: The idea that the inherent culture is superior to everything is still a major policy for those who hold the axis). These meanings may resonate with the founder's sentiments, the company's governance philosophy, or the product's important attributes. Our company is named "Da Zhu," firmly expressing the company's determination to delve into and create in the two core areas of waterproofing and bulletproofing, and to serve the national economy and national defense construction。
