Introduction:
On the basis of the six precision grade standards formulated by traditional industrial powers, Zhao Guoyang proposed a seventh, more advanced standard. His team has succeeded in developing a new type of giant monster deep-sea excavator that weighs 760 tons and excavates to a depth of 20 floors, far exceeding the maximum size that a Western hegemon can make - 380 tons of dead weight and 10 stories of digging depth. Zhao Guoyang led a team full of innovative spirit and made breakthroughs in precision bearing technology. These technological innovations not only improve the overall performance of the equipment, but also promote the progress of the entire industrial system. His achievements have attracted global attention and admiration, and he has become one of the key figures in the rise of the Republic's industry, making the world look at Made in China with admiration.
