Water never forgets its source, only when it is far away can it flow long; trees never leave their roots, only when they are deep can they grow luxuriant leaves. The main purpose of Compiling "seventy years of Changda construction" is: to recognize the historical traces, explore the development motivation, and promote the enterprise to a higher level by measuring the enterprise's progress; to inspire the newcomers to go to tomorrow with a new style by highlighting the achievements of the predecessors, drawing on the experience of the predecessors, and drawing strength from looking back; to fully affirm the historical status and contribution of "Changda", and to stimulate Inspire the spirit of employees, inspire their sense of pride and sense of responsibility of the master, and then look forward to the future with high spirits, ride the wind and waves and start again, to depict newer and more beautiful pictures. He said that the current history of the group is recorded through the annual corporate Yearbook, which is full of contents and faithfully records the development of the group in each year, and is a valuable wealth left in the history of the group. However, due to the limitations of the genre, it is difficult to run through the 70 year development process of the enterprise, reflect the changes in different historical periods, and systematically summarize the success or failure. For this reason, we invited Comrade Li Xiaoming, the former assistant mayor of Weifang City, to be the editor in chief. From the perspective of a third person, on the basis of the Enterprise Yearbook, we compiled "seventy years of Changda construction" in the form of enterprise development history. It is hoped that "seventy years of the construction of Changda" will become a historical monument recording the selfless contributions of the "Changda" people of all dynasties, a historical classic that condenses the spirit of "Changda", demonstrates the contributions of the predecessors and guides the future generations to advance, a precious gift for the 70th birthday of "Changda", and a stepping stone for greater achievements tomorrow. &Comrade Li Xiaoming, editor in chief, briefly introduced the basic context, framework and compilation plan of "seventy years of Changda construction". Since then, the compilation of "seventy years of Changda construction" has officially started. < br / > < br / > < br / >
