At Tianying Cylinder Liner Co., Ltd., Mao Chaofeng inquired in detail about the production and operation of the company. When he learned that the company had not been doing much for several years, the product quality had not been improved, and he was eager to borrow a ship to go to sea and leverage on development, Mao Chaofeng immediately wrote to the "leading boss" of cylinder liner production in Asia-the boss of Zhongyuan Internal Distribution , And call to contact cooperation matters. Mao Chaofeng said that functional units such as the National Development and Reform Commission and the Bureau of Industry must often go deep into the company to understand what the company thinks, needs, and what is urgent, so as to help the company solve its practical difficulties. It is necessary to study industrial planning, industrial layout, and industrial integration; it is necessary to help enterprises to do a good job in technological transformation, product upgrades, and promote them to become bigger and stronger. Mao Chaofeng said that the machinery manufacturing industry has eternal vitality and has been enduring for hundreds of years. Fugou's cylinder head and Xihua's cylinder liner have many years of production history and a certain market share. Relevant departments must study resource integration and industrial combination, form scale advantages, and cultivate new industrial clusters.
