Since the reform and opening up, with a vague concept to sell in China's enterprises are not fully understood, and play an important role. Into the current era, this is a very competitive era, numerous enterprises to survive. Stood out in many companies, in addition to those who have a good business decision-making than planning, I am afraid that the implementation of the implementation of marketing programs to deal directly with customers or business personnel. Economically developed countries in the commodity that the "marketing work is the lifeblood of business," "familiar with the economic environment and the players to cope with changes in the market" and "new product recommendations and developers." 1960, American Marketing Association, said that marketing is a method of artificially or non-human assistance and to persuade customers to buy a product or service, and in accordance with the commercial significance of the sale of the views of those favorable action. World-renowned experts in European marketing Goldman believes that: marketing is to make the customer believe that his purchase of your product is going to get some benefits. Japan, the god of the original one level to promote the motto: marketing is the passion that is hard work fighting ﹑ ﹑ ﹑ that patience is the persistent pursuit of ﹑ is the time of the devil, that is courage. Selling what is it? Simple way to attempt to state its definition, will inevitably lead to biased results. To express this concept more clearly, we analyze the meaning of the two levels. ﹑ Life and promote a Second, business marketing ﹑ Industrial and commercial enterprises in the economic field refers to potential customers and promote sales of goods of a professional activity. Refers to the industrial and commercial enterprises operating in a certain environment, its sales target for a series taken by the process of promotions and activities. Strictly speaking, the form can be divided into two categories. 1. Non-personal selling This includes various publicity media ﹑ sell advertising, public relations and other forms. With the development of social and economic ﹑ technology, and now marketing in the form faster, broader, regardless of time ﹑ area (in addition to TV shopping), more products through the Internet to publicize and promote the customer. Non-personal selling advertising in the form of one of the most important. As a rule that can be called to spend money advertising and publicity. With the development of society, increasingly fierce market competition, advertising, circulation marketing has become an indispensable means within. In fact, many of our small and medium enterprises are good at not understand and do not use advertising to increase sales. I think the main SMEs pulled one hand advertising or sponsorship of the sky called the price scare, or want to do with economic strength, because too much out of advertising content to give up; the other person in charge of business management is the effect of advertising understanding. 2 ﹑ personal selling Officers and non-personal selling to sell the most fundamental difference lies in the approach ﹑ means and in different forms. People mainly rely on a salesman to sell the subjective dynamic role to play, using a variety of persuasive skills to achieve sales objectives. Personal selling to sell than the others have a more important because the effects of personal selling is often higher than other forms of marketing. And personal selling in the early development of small and medium enterprises in particular of utmost importance. In fact, with the rapid development of the communications industry, and in some advanced countries, some companies use telephone, fax, TV programs, computer network products can order the products sold. From a certain perspective, the efficiency of personal selling too monotonous and slow. Personal selling into the business method of choice <1> rapid distribution of personal selling method: generation (test) off ﹑ ﹑ purchase and sale of semi-procurement. <2> down to earth culture Dealer Law: Some credit payment discount ﹑ ﹑ none other test market. <3> synthetic method: rapid distribution and dealer training at the same time and use. From the above can be analyzed collectively, is to promote the intelligence, or tangible or intangible property, in some ways and means to introduce to each other or a third party to obtain a certain moral or material compensation. Third, sell limit Have been introduced earlier to sell its meaning, the ultimate limit is the limit of things. Said here is to limit the marketing of their potential to solve its efforts to sell. In other words, an enterprise is to enlarge the enterprise resource integration to maximize, to the display business style, and how a country is also to promote the same reason other countries. The limit in a marketing nature, is a faith. If each sales person has to sell the limit of the faith, just as the Red Army Long March through the grass, climb snow-capped mountains are also not back down, overcome all difficulties, beyond nature, beyond his own human weaknesses. Limit the performance of marketing is a mind and a broad mind. Has a limit of a good marketing ideas, he must have "One for all", "all for one person," the first dedication, does not mean and do our utmost to serve the community, business and clients. Limit is also selling a technology, which combines the growth science, marketing, marketing, sociology, psychology, etc. to form an interdisciplinary subject, is a professional career, it is more the traditional concept of people-oriented marketing, humane, more recognition of the subjective initiative with the objective of combining to produce endless power. Sell limit the basic function is to promote the courage and humanity, potential, through the development goals, through their own efforts to learn, develop good habits, and very confident, objective sense of things, know how to resolve difficult problems encountered, the pressure into motivation, make good use of social connections, power to make their action, and executive ability to promote the cause of heights, to play its significance.
