Decoration industry to flourish in the country in recent years. According to the China Building Decoration Association survey: there were 250,000 home decoration companies, architectural decoration industry employing nearly ten million, including engineering and technical staff of 50 people, to absorb surplus rural labor force of nearly 700 million people. Due to the development of architectural decoration industry, led decorative building materials production, circulation Shen industry has taught more than 500 million people. The total number of people engaged in the construction and decoration industry and related industries and even reached 15 million. National Building Decoration Industry Project completed in 2007 value of nearly 550 billion yuan, 170 billion yuan to achieve value added of construction. Gross domestic product (GDP) of about 6.2%. With the development of decoration industry, major institutions have gradually opened up the interior design professional or environmental art and design professionals to adapt to this trend. Various types of long and short term courses interior design is everywhere. This is also reflected from one side of the interior design professional booming. Interior designers also become an emerging class - "gray collar" typical. Interior design is a very professional industry, the need to know more about door-related expertise. But in reality, the phenomenon of a lot of people in the learning process prone to side branches, mostly because too much emphasis on writing, computers and hand-painted performance practices of learning programs, ignoring the relatively dry materials and construction techniques of decoration decorative learning. Required power is different from the usual interior design art design categories, it is built on the foundation of practical engineering brigade. Simply put, it is necessary to get out of absurd but also mesh, the country had to get out of doing it. Program creation. Performance computers and hand-painted on the extension of a suddenly. And "Rhythm. The process, but to do it in practice, do not understand the relevant knowledge of materials and construction, and everything will be" on paper. "Many students learn in school during their performance ability is very good, but also quite beautiful renderings drawn, but if the material with which the performance chart and asked how the construction time, but it is often the answer any of them. The reason for this situation is that usually for materials and construction knowledge and learning is not valued. Many graduates into companies engaged in interior design work, often feel confused when you start working in just, I feel unable to start. The reason for this storm caused the most sense because the concept is not as have expressed a lack of techniques, more because of lack of practice by Yi. ECOWAS said Shen is the lack of practical knowledge of materials and construction aspects. interior design requires artistic beauty, but the interior design of the well can not be seen as simply the slope is an art not build in materials, construction on the basis of interior design is "a source of water." At the same time, the actual budget interior decoration works, quotes, and in the process of communication with customers, no time is not a test of non-invasive design division of materials and construction of knowledge. It is no exaggeration to say that the lack of knowledge of designer materials and construction must not be considered a qualified designer.
