Because single-mindedness can focus, because concentration can be professional, because professionalism can reflect value. For example, during this epidemic, why did people want to listen to Zhong Nanshan and Zhang Wenhong? This "obedience" is based on their professional trust. Since its establishment, Qinggeer Information has been serving the wall-hung boiler industry and has been working hard in the wall-hung boiler industry. From the publication of "Heating Information" newspaper, the establishment of China wall-hung boiler industry entrepreneur summer camp, the establishment of China wall-hung boiler industry accessories raw material procurement festival, and the holding of China wall-hung boiler industry after-sales service conference, the comprehensive coverage of the upstream and downstream of the wall-hung boiler industry and the continuous expansion and deepening of industrial service capabilities have continuously injected energy into the industry, continuously enhanced its vitality and made the resource convection smoother. All this depends on the trust of the wall-hung boiler industry in Qinggor information, which is based on the recognition of Qinggor's professional service ability. The development of things generally follows the law of "easy first, then difficult". In the explosive period of industry development, that is, the period of rapid growth, the life of enterprises will be better, and the life of service-oriented enterprises serving the industry will be better. But when the industry develops to a certain extent and the industry market changes from "incremental market" to "stock market", money will become more difficult to earn than in the past. At this time, some service enterprises will think of transformation, horizontal development, and so on. From the perspective of enterprise development, it is understandable to keep looking for new business opportunities and new breakthroughs. However, for enterprises serving a certain industry, its value is reflected because it is professional, and horizontal development means that the original professional ability is "scattered", which will be a great and perhaps irreversible harm to the core competitiveness of such enterprises. In other words, when the professionalism of such enterprises is not enough, its value and the value of its products will naturally be greatly reduced. It is based on this consideration that after the outbreak of 20 17, the wall-hung boiler industry ushered in a cliff-like decline in 20 18. Qinggeer Information still insists on it and still focuses on the wall-hung boiler industry. It is precisely because of this persistence that the after-sales service conference of China wall-hung boiler industry was born in 20 19, which greatly attracted the industry's attention to after-sales service. This is the power of professionalism! It can create great value!
